This example example uses the Arduino board to receive data from the computer. 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.
Software Required
Circuit
Attach an LED to pin 13. The long leg, or anode, goes to pin 13. The short leg, or cathode, goes to ground. You can also use the built-in LED on most Arduino boards.
