This sensor device is built to measure the amount of current being used, especially in power supplies as the design is based on Arduino. The main component used is the ACS712 sensor from Allegro ...

Nowadays, numerous electronic sensor modules are available on the market that can be combined with inexpensive microcontroller boards to measure environmental parameters of importance. The project ...

The folks at Coretech Robotics put together this project. It does take a little skill to build, but nothing too daunting. They used an SR-HC04 sensor because it's cheap and reasonably precise. An ...

“Supplino is a Quick & Dirty PSU (Power Supply Unit) made with some widely available breakout boards, an Arduino Nano (or an Arduino Nano Every) and a graphical LCD. Power output is given by a DC/DC ...

[Artlav] wanted to build a digital camera, but CCDs are expensive and don’t respond well to all wavelengths of light. No problem, then, because with a photodiode, a few stepper motors, the obligatory ...
