Instead of upgrading, [fichl] came up with a device that turns his single channel amp into a completely programmable one, with just an Arduino and a handful of servos. The amp in question – an ...

With just one wire, an Arduino, and some really neat code, [peter] can get this servo to do whatever he wants. First he tells the Arduino the desired duration in frames per second. Then he grabs ...

This DIY solar tracker project mimics this behavior using three simple main components: An Arduino UNO board, a servo motor (with a sunflower paper decoration attached), and two photoresistors ...

The Arduino then interprets this into data that a servo can use to move into position, aligning with the game's location in real time. If you want to look at this project in action, head over to X ...
