We’ve featured loads of IR Arduino projects and they are all exciting and unique. The projects spring from a specific need or problem where a custom infrared remote control is the solution. [… ...

This tutorial will guide you through the process of building a tachometer around an Arduino. Tachometers are used to measure rotation rate in Revolutions Per Minute (RPM). You don’t need much… ...

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 this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...

What is a rotary encoder? A rotary encoder (RT) is a device that you can rotate infinitely. On most rotary encoders, when you rotate them you will feel a bump (known as steps), and most RTs have about ...

The Code Kit is an Arduino system in a box. It comes with a small rechargeable battery that can power an Arduino-based CodeBit with three inputs and three outputs.

There’s one big problem with the Arduino development environment, also known as an IDE: There’s no network hookup to directly share and browse code you’re writing for these little microcontrollers. It ...

The official Arduino IDE is a dour piece of software designed for uploading code to the ubiquitous and super-cool micro controller. It is a standalone, non-networked app that isn’t very pretty to look ...
