Over the last decade, the open-source movement has not only transformed the world of software, but also catalyzed a sweeping revolution in hardware tinkering. At the heart of this shift lies a ...

This article describes how to measure MOSFET drain voltage and current. As part of that discussion it outlines how to use several types of current probes, how to identify the correct measurement ...

[Trent M. Wyatt]’s CPUVolt library provides a fast way to measure voltage using no external components, and no I/O pin. It only applies to certain microcontrollers, but he provides example Ar… ...

For instance, you could use an Arduino to build a motion-controlled video camera or to remote control the lights in your sitting room.

Use voltage probes and a current probe with an oscilloscope to measure voltage and current. Power Analyzers are generally the instrument of choice for household appliance power measurements and other ...

You can characterize a semiconductor device to be its own temperature sensor by using an accurate four-wire measurement technique.

Official Arduino Example Tutorials: The Arduino computer software is loaded with tons of examples for you to use in your own code or to run through as a learning experience.

In a previous article, we looked at connecting various kinds of Arduino hardware to your Mac. Here's how to get started programming on them to create your own projects.
