Grove Multi Color Flash LED is connected to D2 pin of Arduino.
I’ve managed to do a simple fade in fade out cycle from the samples but do not get different colors.
int ledPin = 2;
void setup() {
}
void loop() {
// fade in from min to max in increments of 5 points:
for(int fadeValue = 0; fadeValue <= 255; fadeValue +=5) {
// sets the value (range from 0 to 255):
analogWrite(ledPin, fadeValue);
// wait for 30 milliseconds to see the dimming effect
delay(30);
}
// fade out from max to min in increments of 5 points:
for(int fadeValue = 255; fadeValue >= 0; fadeValue -=5) {
// sets the value (range from 0 to 255):
analogWrite(ledPin, fadeValue);
// wait for 30 milliseconds to see the dimming effect
delay(30);
}
}
