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 ...

[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 ...

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 ...

Proper waste sorting is very important for keeping our neighbourhoods clean and saving resources for the future. When we mix ...

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 ...

From AI-powered single-board computers to precision motor control and vision-based navigation, Arduino is stepping into a new era of robotics innovation. Developers now have access to advanced ...

[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 ...
