In this episode of electronics basics we will be having a look at digital potentiometers. You can use them to control any circuit digitally by replacing their mechanical potentiometers with them. But there can be pitfalls when trying to simply replacing the potentiometer. That is why I will tell you all about digital potentiometers which includes how to control them, what kind of current and voltage they can handle and how to properly use them. Let's get started!
