After some poking around he found that there were only two wires used for all of the control buttons, each button only changing the resistance between the two wires.

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 ...

It’s worth noting that the actual USB interface is being done with a stand-alone controller, so the Arduino here is being used purely to drive the lighting effects.

DIY musical instruments are their own thing entirely, but if you're looking for a place to start, Adafruit has a guide to building your own MIDI controller using an Arduino. The OONTZ uses a 3D ...

The Adafruit Gemma measures just 1 inch in size and is powered by an ATtiny85 and programmable with an Arduino IDE over USB, allowing you to create those wearable projects of the future.

As explained by Hackaday, four Arduino-controlled servos are fitted to the pulleys and cables that operate the rotation, angle, and gripping mechanism of the da Vinci's tool.
