Arduino example
#define LED_PIN 14
const int FADE_DURATION = 5000; // 5 seconds to fade in/out
const int HOLD_DURATION = 5000; // 5 seconds at full brightness
void setup() {
pinMode(LED_PIN, OUTPUT);
}
void loop() {
// Fade in
for (int brightness = 0; brightness <= 255; brightness++) {
analogWrite(LED_PIN, brightness);
delay(FADE_DURATION / 255);
}
// Hold at full brightness for 5 seconds
delay(HOLD_DURATION);
// Fade out
for (int brightness = 255; brightness >= 0; brightness--) {
analogWrite(LED_PIN, brightness);
delay(FADE_DURATION / 255);
}
delay(100);
