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… ...

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 ...

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. [… ...

I have started this joystick controller experiment inspired by the need of a simple DIY joystick which could deliver greater flexibility in the possible designs. Hardware component basis is very ...

Funny thing, isn’t it? That you can watch some little blocks moving on an 8×8 LED matrix and recognize the first level of Super Mario Bros. buried in the squares? Developed by a Carnegie Mellon ...
