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 ...

[Labpacks] wanted to build a robot car controlled by his phone. As a Hackaday reader, of course you probably can imagine building the car. Most could probably even write a phone application to do 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 ...

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 ...

At embedded world 2026, Lucy Barnard speaks with Guneet Bedi, Senior Vice President & General Manager at Arduino about latest ...
