Arduino Basic Experiment 2: Breathing Light Experiment

Arduino Basic Experiment 2: Breathing Light Experiment

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
