Tweeting Christmas Tree

Step 16: Program

Plug in your USB cable, make sure that the switch on the Wireless SD board is toggled to "USB" and program the Arduino with the following code:

/*

Tweeting Christmas Tree receiver code
Controls the color of Christmas tree lights

'a' turns red on
'b' turns red off

'c' turns green on
'd' turns green off

'e' turns white on
'f' turns white off

'g' turns other on
'h' turns yother off

*/

int sentDat;

void setup() {
  Serial.begin(9600);   
  pinMode(3, OUTPUT); 
  pinMode(4, OUTPUT); 
  pinMode(5, OUTPUT); 
  pinMode(6, OUTPUT); 
}

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

        //red control
	if(sentDat == 'a'){
  	  digitalWrite(3, HIGH);
	}else if(sentDat == 'b'){
  	  digitalWrite(3, LOW);
	}

        //green control
	if(sentDat == 'c'){
  	  digitalWrite(4, HIGH);
	}else if(sentDat == 'd'){
  	  digitalWrite(4, LOW);
	}

        //blue control
	if(sentDat == 'e'){
  	  digitalWrite(5, HIGH);
	}else if(sentDat == 'f'){
  	  digitalWrite(5, LOW);
	}

        //other control
	if(sentDat == 'g'){
  	  digitalWrite(6, HIGH);
	}else if(sentDat == 'h'){
  	  digitalWrite(6, LOW);
	}

  }
}

When you are done programming it, unplug the USB cable and toggle the switch back to "micro."
