We think it’s a great learning experience to tear back the veil of abstraction and learn a bit more about the hardware found on an Arduino board. This project is a great example. [Scott Daniels] takes ...

I work a lot with high voltages and others frequently replicate my projects, so I often get asked “What voltage is needed?”. That means I need to be able to measure high voltages. Here’s how I do it ...

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 ...

The hardware was assembled by connecting the Arduino UNO R4 WiFi, the PZEM 004T, the current transformer, and the OLED ...

This video talks about the techniques for measuring drain voltage and current. This course will show you how to accurately measure the MOSFET drain voltage and current with the Power Integrations’ ...

Denis Hennessy recently encountered a problem we've all faced: he needed some AAs for a battery-eating gizmo, and he was overwhelmed by the choices available. Ignoring the shiny packaging and its ...
