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 ...

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 ...

[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 ...

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 ...

Arduinoを用いて、デジタル制御で抵抗値を制御する方法を思いついたので、記録する。 目的 抵抗値のデジタル制御は、一般的にデジタルポテンションメータICを使用する。デジタルポテンションメータICは安くて、小型のため、簡単に使うことができる。

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 ...
