Example 2: Serial Triggering

This example uses the same setup for the arduino. The arduino listens to a serial port on your computer with a baud rate of 9600bps. Each time a value of 1 is sent to the serial port a trigger pulse is generated.

  Trigger and blink on serial command.

// the setup function runs once when you press reset or power the board
void setup() {
  pinMode(9, OUTPUT);
  Serial.write("Extender Trigger Example \n")

// the loop function runs forever
void loop()
  if (Serial.available() > 0)
    int value = Serial.read();
    if (value == 1) {
        digitalWrite(9, HIGH);
        digitalWrite(9, LOW);                                  
    else {
      Serial.write("Undefined Input\n");
