Arduino Explained: Random Brightness Using 1 LED

Random numbers are very useful if you need your LEDs or any project to behave differently each time it is run, instead of a definite set of behavior. For this Arduino project, we will set the brightness of an LED with a random value every 100 milliseconds. To achieve this effect, you will need two Arduino functions: random () and randomSeed() Link to the code: https://arduinointro.com/articles/projects/randomizing-led-brightness-using-random-and-randomseed-in-arduino Link to the fade effect (PWM): https://arduinointro.com/articles/projects/become-a-master-of-the-fade-in-fade-out-effect-arduino-style
