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… ...

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 is an easy tutorial showing how you can control the brightness of an LED or adjust the speed of a DC fan using Arduino Board, a small BC547 transistor and a potentiometer.

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

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?

Instructables user MakerBee's alert system uses an Arduino microcontroller and a dual-axis accelerometer. When your washer and dryer stop vibrating, the machine will know and alert you accordingly.
