[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 Arduino ...

I just got my first Arduino board and have already been having a ton of fun with it. Of course, I started with the simple projects so I could learn to walk before running. Here are the first three ...

Arduino Micro has some extra leds that it is tricky to programme. Like almost all Arduinos, has a built-in led – the green one on the left in the photo. And it has a pair of yellow leds – called TX ...

Shift-out: again? Yes, shift-out registers again, now daisy-chained! But let me write down a short foreword. As probably occurs for most of the subjects, especially those related to the Arduino board, ...

Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...
