Flamethrowing Jack-O'-Lantern

Step 14 Program the transmitter

The transmitter is a little bit trickier if you are using a SquidBee setup because it is lacking an ATMEGA chip.

First unplug the XBee shield.

If necessary, add and bootload and the chip.

Then, like the other board, change the power selection jumper to USB, and then upload the following code:

 The circuit:
 * pushbutton attached to pin 2 from +5V
 * 10K resistor attached to pin 2 from ground
 
 This code is in the public domain.

// constants won't change. They're used here to 
// set pin numbers:
const int buttonPin = 2;     // the number of the pushbutton pin
const int ledPin =  13;      // the number of the LED pin

// variables will change:
int buttonState = 0;         // variable for reading the pushbutton status

void setup() {
  // initialize serial communication:
  Serial.begin(9600); 
  // initialize the LED pin as an output:
  pinMode(ledPin, OUTPUT);      
  // initialize the pushbutton pin as an input:
  pinMode(buttonPin, INPUT);     
}

void loop(){
  // read the state of the pushbutton value:
  buttonState = digitalRead(buttonPin);

  // check if the pushbutton is pressed.
  // if it is, the buttonState is HIGH:
  if (buttonState == HIGH) {     
    // turn LED on:    
    digitalWrite(ledPin, HIGH); 
    //transmit a High command to the pumpkin and delay a second so that it does not recieve more than one command
    //per button press
    Serial.println('h');
    delay(1000); 
  } 
  else {
    // turn LED off:
    digitalWrite(ledPin, LOW); 
  }
}

When you are done, unplug the USB, and reconnect the XBee shield. You will also need to swamp back the power jumpers on the Arduino.

Lastly, change both of the TX/RX jumpers on the XBee shield from USB to XBee.
