Unlike open source software, open source hardware still need money

Lets start
![Page 15: Lvl.up](https://reader034.vdocuments.site/reader034/viewer/2022042623/54c863bc4a795937208b45ab/html5/thumbnails/15.jpg)
Microcontroller!
● Read input from sensor● Output to somewhere.● programmable
![Page 16: Lvl.up](https://reader034.vdocuments.site/reader034/viewer/2022042623/54c863bc4a795937208b45ab/html5/thumbnails/16.jpg)
Why not a computer
● GPIO Limit○ Smaller voltage○ Fewer pins
● Did I tell you it sucked at reading analog
![Page 17: Lvl.up](https://reader034.vdocuments.site/reader034/viewer/2022042623/54c863bc4a795937208b45ab/html5/thumbnails/17.jpg)
How about cell phone?
● You can’t easily add more sensor easily● To add sensor to phone you
○ a microcontroller to ○ USB interface (ftdi)○ Sensor○ Maybe battery

Arduino….
● This is the one I work on a lot, Sorry :-(

You can make it on a breadboard!

What not so cool
● Not the most powerful around● Only limited to C/C++● Some of the recent design not so open
![Page 28: Lvl.up](https://reader034.vdocuments.site/reader034/viewer/2022042623/54c863bc4a795937208b45ab/html5/thumbnails/28.jpg)

Lets Talk Component
![Page 30: Lvl.up](https://reader034.vdocuments.site/reader034/viewer/2022042623/54c863bc4a795937208b45ab/html5/thumbnails/30.jpg)
Where to get components!
Online shop! Go to the earlier slide
p.s pasar road is good too, the experience varies from people to people
![Page 31: Lvl.up](https://reader034.vdocuments.site/reader034/viewer/2022042623/54c863bc4a795937208b45ab/html5/thumbnails/31.jpg)
You can get premade component
![Page 32: Lvl.up](https://reader034.vdocuments.site/reader034/viewer/2022042623/54c863bc4a795937208b45ab/html5/thumbnails/32.jpg)
There is also shield to make prototyping easy
![Page 33: Lvl.up](https://reader034.vdocuments.site/reader034/viewer/2022042623/54c863bc4a795937208b45ab/html5/thumbnails/33.jpg)
Some Pre-assembled one.
![Page 34: Lvl.up](https://reader034.vdocuments.site/reader034/viewer/2022042623/54c863bc4a795937208b45ab/html5/thumbnails/34.jpg)
To use pre-assembled component
1. Find if someone already use it!2. If not start here. Read data sheet3. Understand what you have4. Find out any extra component needed5. Now connect it
![Page 35: Lvl.up](https://reader034.vdocuments.site/reader034/viewer/2022042623/54c863bc4a795937208b45ab/html5/thumbnails/35.jpg)
The internet part
● You essentially have interface to the world● Provide
○ API to read/write○ used by device○ UI to explore data
● 2 main one○ Xively○ thingspeak, it’s open source!

What next
● Go on and explore!● Make stuff, anything!
○ Except killer robot that attack human● I did not do a lot of stuff. But there is a lot
more people done!●

Idea
● Maybe we can map out pollution in KL ;-)● A christmas light that light up with more
facebook like?● Get more inspiration on learning page
