Let's start with DC voltage, one of the simplest and most-used multimeter measurements. The DC voltage measurement is used to determine the difference in electrical potential between two points in a ...

This multimeter add-on is called the Half Ohm. It allows you to measure small resistance values, and can be used to track down shorts on a PCB. The board acts as a pass-through for both probes. When ...

This project implements a Digital Multimeter (DMM) using an AVR microcontroller. It measures voltage (AC/DC), current, and resistance, with results displayed on an LCD. User interaction is handled via ...
