Flamethrowing Jack-O'-Lantern

Step 13: Program the Receiver

Open the SquidBee transmitter node and remove the Arduino from the XBee shield.

Change the power jumper on the Arduino to select USB power (if necessary).

Program the Arduino with the following code:

//Flamethrowing Jack-O'-Lantern Receiver code
//Copyleft 2011

int sentDat;

void setup() {
  Serial.begin(9600);   
  pinMode(3, OUTPUT); 
}

void loop() {
  if (Serial.available() > 0) {
	sentDat = Serial.read(); 

	if(sentDat == 'h'){
          //activate the pumpkin for one second and then stop
  	  digitalWrite(3, HIGH);
          delay(1000);
          digitalWrite(3, LOW);
	}
  }
}

When done, disconnect the USB power, change the power selection jumper, and plug the XBee shield back in.
