A handy little tool that can help you out if you work with LED’s a lot, especially if you are always trying to work out the right resistor to make them work. The ...

[mircemk] built a slick-looking LED tester with a couple handy functions built in. Not only can one select a target current to put through an LED, but by providing a target voltage, the system will ...

Most advanced electronics PCB assembly lines have pick and place machines to pick components from an SMD reel and place it on a PCB. But this is not possible when you are doing medium-scale production ...

This project is an Arduino Nano compatible 18650 battery capacity tester. It can discharge a cell, measure voltage and current, estimate capacity in mAh, and monitor temperature with thermistors for ...

Messing around with Arduino can lead to some fun projects — like simple electronic games, lighting or audio manipulation, or even gesture controls for other devices. However, you'll need the right ...
