Physical Pixel
An example of using the Arduino board to receive data from the
computer. In this case, the Arduino boards turns on an LED when
it receives the character 'H', and turns off the LED when it
receives the character 'L'.
The data can be sent from the Arduino serial monitor, or another
program like Processing (see code below), Flash (via a serial-net
proxy), PD, or Max/MSP.
The circuit:
