Multiple functions in a single push switch using Arduino

Introduction Did you run out of input pins? Don’t worry, here is a solution without any shift registers. In this video, we are going to learn about connecting more than 100 switches to a single pin of Arduino. Working Theory Take a look at the circuit diagram first, otherwise, you won’t be able to understand
