This course will become read-only in the near future. Tell us at community.p2pu.org if that is a problem.
A challenge for members of the "Arduino: Build and Hack the Planet" course: http://p2pu.org/en/groups/arduino-build-and-hack-the-planet/
Learn how to program the planet with open-source hardware and electronic circuits.
An Arduino electronics board with multi-colored lights will be livestreamed over the internet for submitters without their own.
WITH YOUR OWN ARDUINO
Attach lights to two different pins, wire them in a circuit, and program lights to turn on and off!
WITH CROWDBOT
Look at the sample program on http://mapmeld.appspot.com/crowdbot to see where each light is attached, then submit a program through the form.
