ABOUT THE SPEAKER
Massimo Banzi - Physical Computing Guru
Massimo Banzi co-founded Arduino, which makes affordable open-source microcontrollers for interactive projects, from art installations to an automatic plant waterer.

Why you should listen

Computer-based interactivity used to be beyond the reach of most artists, designers, and other electronics amateurs who wanted to make their work respond to light, sound and other stimulus by moving, beeping, tweeting. Then, in 2005, Italian engineer Massimo Banzi and his team created the Arduino microcontroller, a small, cheap programmable computer, bringing interactive technology to the masses.

With a variety of sensors, the Arduino is versatile and easy to use. Since its inception, the device has popped up in projects as varied as an exhibit on brains at the American Museum of Natural History in New York, to a DIY kit that sends a Tweet when your houseplant needs water.

So a few weeks ago, a friend
0
25
2697
00:18
of mine gave this toy car to his
1
2722
2254
00:20
8-year-old son.
2
4976
1611
00:22
But instead of going into a store and buying one,
3
6587
2821
00:25
like we do normally, he went to this
4
9408
2795
00:28
website and he downloaded
5
12203
1915
00:30
a file, and then he printed it
6
14118
2169
00:32
on this printer.
7
16287
1855
00:34
So this idea that you can
8
18142
1979
00:36
manufacture objects
9
20121
1947
00:37
digitally using these machines
10
22068
1563
00:39
is something that The Economist magazine
11
23631
1678
00:41
defined as the Third Industrial Revolution.
12
25309
2630
00:43
Actually, I argue that there is another revolution
13
27939
3843
00:47
going on, and it's the one that has to do with
14
31782
2598
00:50
open-source hardware and the maker's movement,
15
34380
2528
00:52
because the printer that my friend used
16
36908
3759
00:56
to print the toy is actually open-source.
17
40667
2617
00:59
So you go to the same website, you can download all the files
18
43284
3493
01:02
that you need in order to make that printer:
19
46777
3757
01:06
the construction files, the hardware, the software,
20
50534
3512
01:09
all the instruction is there.
21
54046
2809
01:12
And also this is part of a large
22
56855
2120
01:14
community where there are thousands of people
23
58975
2600
01:17
around the world that are actually
24
61575
1960
01:19
making these kinds of printers,
25
63535
1543
01:20
and there's a lot of innovation
26
65078
1472
01:22
happening because it's all open-source.
27
66550
1914
01:24
You don't need anybody's permission to create something great.
28
68464
3888
01:28
And that space is like
29
72352
2361
01:30
the personal computer in 1976,
30
74713
2796
01:33
like the Apples with the other companies are fighting,
31
77509
2357
01:35
and we will see in a few years,
32
79867
2381
01:38
there will be the Apple of this kind of market come out.
33
82248
3127
01:41
Well, there's also another interesting thing.
34
85381
3803
01:45
I said the electronics are open-source, because at the heart
35
89184
1964
01:47
of this printer there is something I'm really attached to:
36
91148
2981
01:50
these Arduino boards, the motherboard that sort of
37
94129
2951
01:52
powers this printer, is a project
38
97080
2207
01:55
I've been working on for the past seven years.
39
99287
2423
01:57
It's an open-source project.
40
101710
1561
01:59
I worked with these friends of mine that I have here.
41
103271
3021
02:02
So the five of us, two Americans, two Italians
42
106292
2654
02:04
and a Spaniard, we — (Laughter)
43
108946
2981
02:07
You know, it's a worldwide project. (Laughter)
44
111927
3075
02:10
So we came together in this
45
115002
1869
02:12
design institute called the Interaction Design Institute
46
116871
2623
02:15
Ivrea, which was teaching
47
119494
2149
02:17
interaction design, this idea that you can take
48
121643
2298
02:19
design from the simple shape
49
123941
2551
02:22
of an object and you can move it
50
126492
1777
02:24
forward to design the way you interact with things.
51
128269
2044
02:26
Well, when you design an object that's supposed to interact
52
130321
2892
02:29
with a human being, if you make a foam model
53
133213
1808
02:30
of a mobile phone, it doesn't make any sense.
54
135021
2823
02:33
You have to have something that
55
137844
1506
02:35
actually interacts with people.
56
139350
2507
02:37
So, we worked on Arduino and
57
141857
3119
02:40
a lot of other projects there to
58
144976
1816
02:42
create platforms that would be
59
146792
1901
02:44
simple for our students to use,
60
148693
2184
02:46
so that our students could just build things that worked,
61
150877
2461
02:49
but they don't have five years to become an electronics engineer. We have one month.
62
153338
4058
02:53
So how do I make something that even a kid can use?
63
157396
2655
02:55
And actually, with Arduino,
64
160051
2901
02:58
we have kids like Sylvia that you see here,
65
162952
2423
03:01
that actually make projects with Arduino.
66
165375
1872
03:03
I have 11-year-old kids stop me and show me
67
167247
2608
03:05
stuff they built for Arduino that's really
68
169855
2819
03:08
scary to see the capabilities
69
172674
1741
03:10
that kids have when you give them the tools.
70
174415
2423
03:12
So let's look at what happens when you make a tool
71
176838
2980
03:15
that anybody can just pick up and build something quickly,
72
179818
2844
03:18
so one of the examples that I like to sort of
73
182665
1868
03:20
kick off this discussion is this
74
184533
1914
03:22
example of this cat feeder.
75
186447
1730
03:24
The gentleman who made this project had two cats.
76
188177
2567
03:26
One was sick and the other one
77
190744
1734
03:28
was healthy, so he had to make
78
192478
2378
03:30
sure they ate the proper food.
79
194856
1688
03:32
So he made this thing that recognizes the cat
80
196544
2159
03:34
from a chip mounted inside
81
198703
2137
03:36
on the collar of the cat, and opens the door
82
200840
2720
03:39
and the cat can eat the food.
83
203560
1744
03:41
This is made by recycling an old CD player
84
205304
1790
03:42
that you can get from an old computer,
85
207094
2207
03:45
some cardboard, tape, couple of sensors, a few blinking LEDs,
86
209307
3456
03:48
and then suddenly you have a tool. You build something
87
212763
2788
03:51
that you cannot find on the market.
88
215551
1937
03:53
And I like this phrase: "Scratch your own itch."
89
217488
2764
03:56
If you have an idea, you just go and you make it.
90
220252
2595
03:58
This is the equivalent of sketching on paper
91
222847
1949
04:00
done with electronics.
92
224796
2572
04:03
So one of the features that I
93
227368
1748
04:05
think is important about our work
94
229116
1828
04:06
is that our hardware, on top of
95
230944
2772
04:09
being made with love in Italy —
96
233716
2190
04:11
as you can see from the
97
235906
1753
04:13
back of the circuit — (Laughter)
98
237659
2029
04:15
is that it's open,
99
239688
1840
04:17
so we publish all the design
100
241528
1968
04:19
files for the circuit online,
101
243496
1728
04:21
so you can download it and
102
245224
1983
04:23
you can actually use it to
103
247207
1840
04:24
make something, or to modify, to learn.
104
249047
2633
04:27
You know, when I was learning about programming,
105
251680
1269
04:28
I learned by looking at other people's code,
106
252949
1877
04:30
or looking at other people's circuits in magazines.
107
254826
3429
04:34
And this is a good way to learn,
108
258255
2216
04:36
by looking at other people's work.
109
260471
2241
04:38
So the different elements of the project are all open,
110
262712
2592
04:41
so the hardware is released
111
265304
1703
04:42
with a Creative Commons license.
112
267007
2064
04:44
So, you know, I like this idea that hardware becomes
113
269071
2026
04:46
like a piece of culture that you share
114
271097
2139
04:49
and you build upon, like it was
115
273236
1959
04:51
a song or a poem with Creative Commons.
116
275195
3637
04:54
Or, the software is GPL, so it's open-source as well.
117
278832
2676
04:57
The documentation and the hands-on teaching
118
281508
3427
05:00
methodology is also open-source and released as the Creative Commons.
119
284935
3583
05:04
Just the name is protected so
120
288518
2003
05:06
that we can make sure that we can tell people
121
290521
2746
05:09
what is Arduino and what isn't.
122
293267
2640
05:11
Now, Arduino itself is made of
123
295907
1672
05:13
a lot of different open-source components
124
297579
2240
05:15
that maybe individually are hard to use for
125
299819
2751
05:18
a 12-year-old kid, so Arduino
126
302570
2107
05:20
wraps everything together into
127
304677
1853
05:22
a mashup of open-source technologies
128
306530
2266
05:24
where we try to give them the
129
308796
1872
05:26
best user experience to get something done quickly.
130
310668
2207
05:28
So you have situations like this,
131
312875
2871
05:31
where some people in Chile
132
315746
1938
05:33
decided to make their own boards instead of buying them,
133
317684
2792
05:36
to organize a workshop and
134
320482
1925
05:38
to save money. Or there are
135
322407
3100
05:41
companies that make their own
136
325507
1945
05:43
variations of Arduino that fit
137
327452
1769
05:45
in a certain market, and there's
138
329221
1751
05:46
probably, maybe like a 150 of them
139
330972
2713
05:49
or something at the moment.
140
333685
1792
05:51
This one is made by a company
141
335477
1888
05:53
called Adafruit, which is run by
142
337365
1944
05:55
this woman called Limor Fried,
143
339309
2312
05:57
also known as Ladyada, who is
144
341621
1607
05:59
one of the heroes of the open-source hardware movement
145
343228
2721
06:01
and the maker movement.
146
345949
1534
06:03
So, this idea that you have a new, sort of
147
347483
2954
06:06
turbo-charged DIY community
148
350437
2784
06:09
that believes in open-source,
149
353221
1680
06:10
in collaboration, collaborates
150
354901
2200
06:13
online, collaborates in different spaces.
151
357101
2441
06:15
There is this magazine called Make that sort of gathered
152
359542
3122
06:18
all these people and sort of put them together
153
362664
1540
06:20
as a community, and you see
154
364204
2432
06:22
a very technical project explained in a
155
366636
2028
06:24
very simple language, beautifully typeset.
156
368664
2857
06:27
Or you have websites,
157
371521
1568
06:28
like this one, like Instructables,
158
373089
2261
06:31
where people actually teach each other about anything.
159
375350
2004
06:33
So this one is about Arduino projects,
160
377354
1745
06:34
the page you see on the screen, but effectively here you can
161
379099
3561
06:38
learn how to make a cake and everything else.
162
382660
2578
06:41
So let's look at some projects.
163
385238
2800
06:43
So this one is a quadcopter.
164
388038
1616
06:45
It's a small model helicopter.
165
389654
1715
06:47
In a way, it's a toy, no?
166
391369
2270
06:49
And so this one was military technology
167
393639
2293
06:51
a few years ago, and now it's
168
395932
1921
06:53
open-source, easy to use, you can buy it online.
169
397853
2642
06:56
DIY Drones is the community; they do this thing called ArduCopter.
170
400495
3918
07:00
But then somebody actually launched this start-up called
171
404413
3011
07:03
Matternet, where they figured out that you could
172
407426
2193
07:05
use this to actually transport
173
409619
2298
07:07
things from one village to another in Africa,
174
411917
2433
07:10
and the fact that this was easy to find,
175
414350
1568
07:11
open-source, easy to hack, enabled them
176
415918
2612
07:14
to prototype their company really quickly.
177
418530
2138
07:16
Or, other projects. Matt Richardson: I'm getting a little sick
178
420668
2689
07:19
of hearing about the same people on TV over and over and over
179
423357
3256
07:22
again, so I decided to do something about it.
180
426613
3210
07:25
This Arduino project,
181
429823
1414
07:27
which I call the Enough Already, will mute the TV anytime
182
431237
3362
07:30
any of these over-exposed
183
434612
1975
07:32
personalities is mentioned. (Laughter)
184
436587
1232
07:33
I'll show you how I made it. (Applause)
185
437819
4848
07:38
MB: Check this out.
186
442667
1824
07:40
MR: Our producers caught up with Kim Kardashian earlier
187
444491
1957
07:42
today to find out what she was planning on wearing to her —
188
446448
2903
07:45
MB: Eh? (Laughter)
189
449351
1391
07:46
MR: It should do a pretty good
190
450742
1902
07:48
job of protecting our ears from having to hear about the details
191
452644
1667
07:50
of Kim Kardashian's wedding.
192
454311
1796
07:52
MB: Okay. So, you know, again, what is interesting here
193
456107
4557
07:56
is that Matt found this module
194
460664
2970
07:59
that lets Arduino process
195
463634
2232
08:01
TV signals, he found some code
196
465866
1889
08:03
written by somebody else that generates infrared signals for the TV,
197
467755
2829
08:06
put it together and then created this great project.
198
470584
2350
08:08
It's also used, Arduino's used,
199
472934
2052
08:10
in serious places like, you know, the Large Hadron Collider.
200
474986
2887
08:13
There's some Arduino balls collecting data and sort of
201
477886
2709
08:16
measuring some parameters.
202
480595
1800
08:18
Or it's used for —
203
482395
2319
08:20
(Music)
204
484714
10712
08:31
So this is a musical interface
205
495426
2441
08:33
built by a student from Italy,
206
497867
2119
08:35
and he's now turning this into
207
499986
2120
08:38
a product. Because it was a
208
502106
1858
08:39
student project becoming a product.
209
503964
2231
08:42
Or it can be used to make an assistive device.
210
506195
1944
08:44
This is a glove that understands
211
508139
1990
08:46
the sign language and transforms
212
510129
2147
08:48
the gestures you make into sounds
213
512276
2199
08:50
and writes the words that you're signing on a display
214
514475
3316
08:53
And again, this is made of all different parts you can find
215
517791
1346
08:55
on all the websites that sell Arduino-compatible parts,
216
519137
2949
08:57
and you assemble it into a project.
217
522086
2084
09:00
Or this is a project from the ITP part of NYU,
218
524170
3321
09:03
where they met with this boy
219
527491
1727
09:05
who has a severe disability, cannot play with the PS3,
220
529218
3017
09:08
so they built this device that
221
532236
1943
09:10
allows the kid to play baseball
222
534179
2447
09:12
although he has limited
223
536626
1897
09:14
movement capability.
224
538523
2376
09:16
Or you can find it in arts projects.
225
540899
2150
09:18
So this is the txtBomber.
226
543049
2315
09:21
So you put a message into this device
227
545364
1637
09:22
and then you roll it on the wall, and it basically
228
547001
2843
09:25
has all these solenoids
229
549844
1902
09:27
pressing the buttons on spray cans,
230
551746
1792
09:29
so you just pull it over a wall
231
553538
1636
09:31
and it just writes on the wall
232
555174
1727
09:32
all the political messages.
233
556901
2462
09:35
So, yeah. (Applause)
234
559363
2631
09:37
Then we have this plant here.
235
561994
2040
09:39
This is called Botanicalls,
236
564034
1890
09:41
because there's an Arduino ball with a Wi-Fi module
237
565924
3195
09:45
in the plant, and it's measuring
238
569119
2601
09:47
the well-being of the plant,
239
571720
1515
09:49
and it's creating a Twitter account
240
573235
1990
09:51
where you can actually interact with the plant. (Laughter)
241
575225
3529
09:54
So, you know, this plant
242
578754
1930
09:56
will start to say, "This is really hot," or
243
580684
2479
09:59
there's a lot of, you know, "I need water right now." (Laughter)
244
583163
4071
10:03
So it just gives a personality to your plant.
245
587234
3423
10:06
Or this is something that twitters when the
246
590657
2667
10:09
baby inside the belly of a
247
593324
1966
10:11
pregnant woman kicks. (Laughter)
248
595290
2608
10:13
Or this is a 14-year-old kid in
249
597898
1591
10:15
Chile who made a system that
250
599489
2120
10:17
detects earthquakes and publishes on Twitter.
251
601609
2324
10:19
He has 280,000 followers.
252
603933
2488
10:22
He's 14 and he anticipated
253
606421
2144
10:24
a governmental project by one year. (Applause)
254
608565
3639
10:28
Or again, another project where,
255
612204
3741
10:31
by analyzing the Twitter feed
256
615945
1746
10:33
of a family, you can basically
257
617691
1936
10:35
point where they are, like in the "Harry Potter" movie.
258
619627
2742
10:38
So you can find out everything about this project on the website.
259
622369
2816
10:41
Or somebody made a chair that twitters when somebody farts. (Laughter)
260
625185
4681
10:45
It's interesting how, in 2009,
261
629866
3083
10:48
Gizmodo basically defined,
262
632949
2382
10:51
said that this project actually gives a meaning to Twitter,
263
635331
2763
10:53
so it was — a lot changed in between. (Laughter)
264
638094
3261
10:57
So very serious project.
265
641355
1444
10:58
When the Fukushima disaster happened,
266
642799
2207
11:00
a bunch of people in Japan, they realized that the information
267
645006
3002
11:03
that the government was giving wasn't really open
268
648008
2555
11:06
and really reliable, so they built
269
650563
1750
11:08
this Geiger counter, plus Arduino, plus network
270
652313
2776
11:10
interface. They made 100
271
655089
1932
11:12
of them and gave them to people around Japan, and essentially
272
657021
3565
11:16
the data that they gathered gets published on this website
273
660599
2260
11:18
called Cosm, another website
274
662859
2149
11:20
they built, so you can actually get reliable real-time
275
665008
3641
11:24
information from the field,
276
668649
1825
11:26
and you can get unbiased information.
277
670474
3607
11:29
Or this machine here, it's from
278
674081
1883
11:31
the DIY bio movement,
279
675964
2440
11:34
and it's one of the steps that you need in order to process DNA,
280
678404
2324
11:36
and again, it's completely open-source from the ground up.
281
680728
3378
11:40
Or you have students in developing countries making
282
684106
3392
11:43
replicas of scientific instruments that cost
283
687500
2989
11:46
a lot of money to make.
284
690489
1911
11:48
Actually they just build them themselves for a lot less
285
692400
2590
11:50
using Arduino and a few parts.
286
694990
1233
11:52
This is a pH probe.
287
696223
1896
11:54
Or you get kids, like these kids, they're from Spain.
288
698119
3398
11:57
They learned how to program and to make robots when they
289
701517
2858
12:00
were probably, like, 11, and then they started to use Arduino
290
704381
2669
12:02
to make these robots that play football. They became
291
707050
1993
12:04
world champions by making an Arduino-based robot.
292
709043
2842
12:07
And so when we had to make
293
711885
1876
12:09
our own educational robot, we just went to them and said,
294
713761
2810
12:12
you know, "You design it, because you know exactly
295
716573
2348
12:14
what is needed to make a great robot that excites kids."
296
718921
3730
12:18
Not me. I'm an old guy.
297
722651
1676
12:20
What am I supposed to excite, huh? (Laughter)
298
724327
2536
12:22
But as I — in terms of educational assets. (Laughter)
299
726863
3935
12:26
There's also companies like Google
300
730798
1898
12:28
that are using the technology
301
732696
1951
12:30
to create interfaces between
302
734647
2874
12:33
mobile phones, tablets and the real world.
303
737521
3393
12:36
So the Accessory Development Kit
304
740914
1020
12:37
from Google is open-source
305
741934
2052
12:39
and based on Arduino, as opposed
306
743986
1382
12:41
to the one from Apple which is
307
745368
1657
12:42
closed-source, NDA, sign your
308
747025
2504
12:45
life to Apple. Here you are.
309
749529
2565
12:47
There's a giant maze, and Joey's sitting there, and the
310
752094
2580
12:50
maze is moving when you tilt the tablet.
311
754674
4184
12:54
Also, I come from Italy, and the design is important
312
758858
2971
12:57
in Italy, and yet very conservative.
313
761830
2347
13:00
So we worked with a design
314
764177
1417
13:01
studio called Habits, in Milan,
315
765594
2166
13:03
to make this mirror, which is completely open-source.
316
767760
2688
13:06
This doubles also as an iPod speaker.
317
770448
3185
13:09
So the idea is that the hardware, the software,
318
773633
3637
13:13
the design of the object, the fabrication,
319
777270
1468
13:14
everything about this project is open-source
320
778738
2485
13:17
and you can make it yourself.
321
781223
1870
13:18
So we want other designers to pick this up and learn how
322
783093
2354
13:21
to make great devices, to learn
323
785447
2611
13:23
how to make interactive products
324
788058
1678
13:25
by starting from something real.
325
789736
2769
13:28
But when you have this idea,
326
792505
2401
13:30
you know, what happens to all these ideas?
327
794906
1913
13:32
There's, like, thousands of ideas that I —
328
796819
1878
13:34
You know, it would take seven hours for me to do
329
798697
2160
13:36
all the presentations.
330
800857
1880
13:38
I will not take all the seven hours. Thank you.
331
802737
3048
13:41
But let's start from this example:
332
805785
2016
13:43
So, the group of people
333
807801
1928
13:45
that started this company called Pebble, they prototyped
334
809729
2411
13:48
a watch that communicates via Bluetooth with your phone,
335
812140
3692
13:51
and you can display information
336
815832
1536
13:53
on it. And they prototyped with
337
817368
2272
13:55
an old LCD screen from a Nokia
338
819640
1945
13:57
mobile phone and an Arduino.
339
821585
2408
13:59
And then, when they had a final
340
823993
1833
14:01
project, they actually went to Kickstarter
341
825826
2408
14:04
and they were asking for 100,000 dollars to make
342
828234
2619
14:06
a few of them to sell.
343
830853
1855
14:08
They got 10 million dollars.
344
832708
2071
14:10
They got a completely
345
834779
1535
14:12
fully funded start-up, and they don't have to,
346
836314
2695
14:14
you know, get VCs involved or anything,
347
839027
1852
14:16
just excite the people with their great project.
348
840879
2833
14:19
The last project I want to show you is this:
349
843747
2284
14:21
It's called ArduSat. It's currently on Kickstarter,
350
846031
3738
14:25
so if you want to contribute, please do it.
351
849769
2307
14:27
It's a satellite that goes into space, which is probably
352
852076
2810
14:30
the least open-source thing you can imagine,
353
854886
1922
14:32
and it contains an Arduino
354
856808
2051
14:34
connected to a bunch of sensors. So if you know how to use Arduino,
355
858859
3110
14:37
you can actually upload your experiments
356
861969
2456
14:40
into this satellite and run them.
357
864425
2191
14:42
So imagine, if you as a high school can have the satellite
358
866616
2636
14:45
for a week and do satellite
359
869252
2349
14:47
space experiments like that.
360
871601
2652
14:50
So, as I said, there's
361
874253
2756
14:52
lots of examples, and I'm going to stop here. And I just
362
877009
1559
14:54
want to thank the Arduino community
363
878568
2516
14:56
for being the best, and just
364
881084
1670
14:58
every day making lots of projects.
365
882754
2192
15:00
Thank you. (Applause)
366
884946
3464
15:04
(Applause)
367
888410
2327
15:06
And thanks to the community.
368
890737
2487
15:09
Chris Anderson: Massimo,
369
893224
1973
15:11
you told me earlier today that you had no idea, of course,
370
895197
2605
15:13
that it would take off like this.
371
897802
1472
15:15
MB: No.
372
899274
789
15:15
CA: I mean, how must you feel when you read this stuff and you
373
900063
1796
15:17
see what you've unlocked?
374
901859
2501
15:20
MB: Well, it's the work of a lot of people, so we as a community
375
904360
2816
15:23
are enabling people to make
376
907179
1794
15:24
great stuff, and I just feel overwhelmed.
377
908973
2484
15:27
It's just, it's difficult to describe this.
378
911475
2169
15:29
Every morning, I wake up and I look at all the stuff that
379
913644
2014
15:31
Google Alerts sends me, and it's
380
915658
2186
15:33
just amazing. It's just
381
917844
1535
15:35
going into every field that you can imagine.
382
919379
2673
15:37
CA: Thank you so much. (Applause)

ABOUT THE SPEAKER
Massimo Banzi - Physical Computing Guru
Massimo Banzi co-founded Arduino, which makes affordable open-source microcontrollers for interactive projects, from art installations to an automatic plant waterer.

Why you should listen

Computer-based interactivity used to be beyond the reach of most artists, designers, and other electronics amateurs who wanted to make their work respond to light, sound and other stimulus by moving, beeping, tweeting. Then, in 2005, Italian engineer Massimo Banzi and his team created the Arduino microcontroller, a small, cheap programmable computer, bringing interactive technology to the masses.

With a variety of sensors, the Arduino is versatile and easy to use. Since its inception, the device has popped up in projects as varied as an exhibit on brains at the American Museum of Natural History in New York, to a DIY kit that sends a Tweet when your houseplant needs water.
