In the previous experiment, we learned about the principle of the running light—multiple LEDs lighting up and turning off in sequence. In this experiment, we will learn how to implement a breathing light using Arduino. Unlike the running light, the breathing light achieves a “breathing” display effect by gradually adjusting the brightness of the LED.1. … Read more
