Bluetooth Image Light Writer



Bluetooth, a simple microcontroller, and an RGB LED. I stream image data over to the micro from Processing, so I can change the color in real time, or by a preset image. It pauses after each row, so I can move the writer to a new position if I’d like. I’ll post more when I get better working with it.

//Bluetooth LightWrite —Dylan Moore 2008. Thanks, arduino!

void setup()

{
    Serial.begin(9600);
}

int r,g,b;
int incomingByte = 0; 

void loop()

{
    //PWM:
    analogWrite(9,r); //R
    analogWrite(11,g); //G
    analogWrite(10,b); //B
    //Serial.println(“heartbeat”);
    if (Serial.available() > 0) 
        {
        incomingByte = Serial.read();
        if(incomingByte==255) //this will be the transition number while (Serial.available()<=0); 
        incomingByte = Serial.read();
        r=incomingByte;
        while(Serial.available()<=0);
        incomingByte = Serial.read(); g=incomingByte;
        while(Serial.available()<=0);
        incomingByte = Serial.read(); b=incomingByte;
        }
}

Arduino I2C

First of all: Do not use Wiring. It, while well intentioned, does not do what it should. I have appropriated a chunk of code from the avrlibc library (http://www.nongnu.org/avr-libc/)
