How to control an inverting operational amplifier using Arduino UNO and a digital potentiometer

Leave a Comment / Arduino /

What is an operational amplifier? The operational amplifier (also called opamp) is a solid-state analog electronic component capable, as its name suggests, of amplifying an electrical signal. It is defined as operational because it is able to perform some mathematical operations in a totally analogical way on electrical signals. The generally possible operations are addition,
