=== Week 2 - Digital input/output ===
* light blink example* light fader (external LED)* take a one dimensional output (one light) and communicate valuable information. ** "encoding" ** morse code http://en.wikipedia.org/wiki/Morse_code** Braille (a digital touch encoding), implemented with Servos** http://en.wikipedia.org/wiki/File:Braille_cell.svg** think about contextualization... if the light is in an empty fuel gauge... warning light... how does its meaning change** how could you change the meaning through contextualization** meaning through pattern, over time* registering input* responding to input[[basic_digital]]* changing output based on input* USE USES OF THE ARDUINOON THE WEB:
** to make a 3d scanner http://hackedgadgets.com/2009/04/02/3d-arduino-scanner/
** with 2 servos (to be demonstrated), and an IR range-finder: http://www.acroname.com/robotics/parts/R144-GP2Y0A02YK.html
