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 ...

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

This project mixes the commands sent from the Arduino to the transmitter with the manual input by connecting an Arduino to a Radio Control Transmitter. A trainer cable for the RC transmitter had to be ...

Arduino-fanciers Oomlout have put together a neat control box for the popular prototyping board, complete with five potentiometers and three switches. There's also a software app that can monitor the ...

[Kerry Wong] comes across the coolest hardware, and always manages to do something interesting with it. His widget du jour is an old demo board for a digital RF attenuator chip, which can pad a signal ...

I had to learn to walk before I could run.

[Andrew] is bringing his old mechanical sewing machine into the 21st century by adding an Arduino control module. Originally, his Alfa sewing machine could only do a straight stitch or a zig-zag of ...
