Makers, developers, and hobbyists looking for a way to measure both voltage and current simultaneously may be interested in a new Arduino project published on the official Arduino blog. This project ...

You don’t see them much anymore, but there was a time when any hobbyist who dealt with RF probably had a grid dip meter. The ...

Current sensing is used to perform two essential circuit functions. First, it is used to measure “how much” current is flowing in a circuit, which may be used to make decisions about turning off ...

A multimeter and its test leads allow electrical workers to reach into an energized panel, touch live circuit components with the end of the test leads, and capture electrical readings like voltage, ...

If you're seeking a way to measure current and power in a circuit, you need to know about current-sense amplifiers (CSAs). A CSA is a specialized op amp connected as differential amplifier with ...

Modern digital multimeters (DMMs) are user-friendly, accurate, and safe — when used correctly! Reading voltage is simple, but measurements must be properly interpreted. With a clamp-on DMM, accurate ...
