There are easy ways of getting more I/O pins for any project; shift registers, I2C expanders, or ADCs will give you plenty of pins for whatever project you have in mind. All these require extra ...

An automatic toll gate system using Arduino revolutionises traditional toll collection by eliminating manual intervention.

[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 ...

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 ...

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 ...

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. In order to program your ...

When you think of Arduino, your mind immediately pictures an Arduino Uno with its teal color, bulky USB port, and long microcontroller chip sitting on a socket, and you're not alone. The Uno is such a ...
