A little bit of theory

Arduino blinking LED

* install Arduino: http://arduino.cc/en/Main/Software#toc2
* do the blinking LED tutorial: http://arduino.cc/en/Tutorial/Blink
* do the Fade tutorial: http://arduino.cc/en/Tutorial/Fade

So what did we do: Volts & Amps & Ohms & Power

* A water analogy: http://wdka.simbits.nl/w2/img4.html
* Ohm's law
* Calculate the LED resistor
