Here's the first thing I programmed up with my new Arduino! (I'm not new to Atmel μcontrollers but new to the Arduino) It's just a
diffused RGB LED that goes red-green-blue-yellow-purple-turquoiseish (last one was supposed to be white, got tired of fiddling with it). Figured I'd post the code since
Sparkfun didn't have a link for an Arduino example, just the
Wiring example I took and modified. All that really needs to change from the example is the PWM pins since they are different on the Arduino.
int RED = 3; // RED pin of the LED to PWM pin 3
int GREEN = 6; // GREEN pin of the LED to PWM pin 6
int BLUE = 5; // BLUE pin of the LED to PWM pin 5
int gw = 0;
void setup()
{
Serial.begin(9600);
}
void loop()
{
for(int r = 0; r < 64; r+=1) {
analogWrite(BLUE, 0);
analogWrite(GREEN, 0);
analogWrite(RED, r);
delay(60);
}
for(int g = 0; g < 64; g+=1) {
analogWrite(BLUE, 0);
analogWrite(RED, 0);
analogWrite(GREEN, g);
delay(60);
}
for(int b = 0; b < 256; b+=4) {
analogWrite(RED, 0);
analogWrite(GREEN, 0);
analogWrite(BLUE, b);
delay(60);
/* Code if you want to "see" what's going on the Serial Monitor, useful for debugging
Serial.print(r);
Serial.print("\t");
Serial.print(g);
Serial.print("\t");
Serial.print(b);
Serial.println();*/
}
for(int y = 0; y < 64; y+=1) {
analogWrite(BLUE, 0);
analogWrite(RED, y);
analogWrite(GREEN, y);
delay(60);
}
for(int p = 0; p < 64; p+=1) {
analogWrite(BLUE, p);
analogWrite(RED, p);
analogWrite(GREEN, 0);
delay(60);
}
for(int w = 0; w < 64; w+=1) {
analogWrite(BLUE, w);
analogWrite(RED, 0);
gw=w;
if(gw != 0)
gw+=5;
analogWrite(GREEN, gw);
delay(60);
}
}
Next I'll be posting about the project that I actually got all this hardware for; note the
Kent Display in the pic :)
