An Arduino is a popular open-source single-board microcontroller. Learn how to program one and let the possibilities take shape.

C isn’t the only programming language for microcontrollers. This article covers the compatible hardware and workflow steps when programming with a different option—MicroPython.

On a microcontroller, though, you’ll have to roll your own CPU load meter with a few parts, some code, and a voltmeter. We like [Dave Marples]’s simple approach to quantifying something as ...

He’s actually crafting the operation codes for a PIC microcontroller by hand. We’re glad he’s explained this in-depth because right now we feel way over our heads.

For beginners learning to program Arduinos, a web-based, fully networked developer environment called Codebender could drastically reduce the learning curve.
