Here is a video of my results from todays efforts, I think it came out OK, although the led is pretty bright so a lot of the color gets blown out:
The code I used was directly based on the example program in the Arduino IDE called Fade. Instead of just fading one LED, now I fade three at different rates.
int brightnessr = 0;
int brightnessg = 0;
int brightnessb = 0;
int fadeAmountr = 1;
int fadeAmountg = 2;
int fadeAmountb = 3;
void setup() {
pinMode(9, OUTPUT);
pinMode(10, OUTPUT);
pinMode(11, OUTPUT);
}
void loop() {
analogWrite(9, brightnessr);
analogWrite(10, brightnessg);
analogWrite(11, brightnessb);
brightnessr = brightnessr + fadeAmountr;
brightnessg = brightnessg + fadeAmountg;
brightnessb = brightnessb + fadeAmountb;
if (brightnessr == 0 || brightnessr == 255) {
fadeAmountr = -fadeAmountr ;
}
if (brightnessg == 0 || brightnessg == 255) {
fadeAmountg = -fadeAmountg ;
}
if (brightnessb == 0 || brightnessb == 255) {
fadeAmountb = -fadeAmountb ;
}
delay(60);
}
I hope to in the future turn this into a full RGB LED sphere, with individually addressable LEDs.
