Xbee Zigbee Network . Doorbell test

Using 2 Xbee Series 2 to run a simple network.

Network 1


Code — Sender:

* and the BELL program on the receiving end
* by Rob Faludi http://faludi.com
*/

#define VERSION "1.00a0"

void setup() {
pinMode(BUTTON, INPUT);
Serial.begin(9600);
}

void loop() {
// send a capital D over the serial port if the button is pressed
if (digitalRead(BUTTON) == HIGH) {

digitalWrite(BELL, LOW);
}
}
}

Network 2 with feedback loop

Basic Doorbell with Feedback
The setup remains the same, but now we are using the LED that is in pin 11 on the Sender (button).  The code is modified in that the receiving Arduino not only rings the bell, but also sends a ‘K’ back to the sender, at which point it lights the LED.
