What would you like to do?
Arduino RGB LED Fire Simulation. Don't look directly into the LED, it is meant to be reflected in something like a model furnace.
// Set the Pins for LED
int green = 10;
int blue = 9;
int red = 11;
void setup()
//Configure Pins as Output
pinMode(green, OUTPUT);
pinMode(blue, OUTPUT);
pinMode(red, OUTPUT);
void loop() {
//Generate Random Number to set brightness
int brightness = random(120);
//Use brightness and filler to set Red to high visibility
analogWrite(red, brightness+135);
//Use green and blue in a very low percentage to get some orange glowing into the "fire"
analogWrite(green, brightness/7);
analogWrite(blue, brightness/17);
//create a little bit of flickering
