Potentiometers are simply termed as POTs and these are even called as variable resistors. The main purpose of a potentiometer is to vary the value of resistance in the circuit. Even these can be employed to vary volume, and dim and brightness of a light. There exist various types of potentiometers such as carbon POTs, wired POTs and plastic POTs. The one type which we are going to discuss today is “Digital Potentiometer”. So, let us discuss more on digital potentiometer definition, how it is des … [Read more...]
