Serial Interface, for debugging

Sketchbook->Examples->Communication->ASCIITable

Serial.print()
Serial.println()

Dimmer

Examples->Communication->Dimmer Controlling a physical LED with the computer. void loop() {

 char val;
 
 // check if data has been sent from the computer
 if (Serial.available()) {
   // read the most recent byte (which will be from 0 to 255)
   val = Serial.read();
   
   if((val>='0')&&(val<='9'))
       analogWrite(ledPin, 25*(val-'0'));
 }

}
