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. [… ...

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 ...

For this, just wire up the hardware (arduino+keypad) as described earlier. Although the code is an entry-level one, it includes a secret key option that will need to be entered on the keypad.

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… ...

The code in loop () is executed repeatedly as long as the power to the Arduino is supplied. Even if you power off the Arduino and power it back on, the sketch still resides until you overwrite it with ...

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 ...

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.
