Recent experiments with the Arduino CapSense library led [Bryan] around the Internet looking for interesting applications. He hit upon a very cool touch scroll wheel made entirely with PCB traces ...

If counterclockwise, the DOWN signal is registered at each step. Luckily, using the mouse scroll wheel encoder with an Arduino Uno proved to be easy after I made a slight modification (see below).

Jumper wires soldered to the circuit board simply allow the Arduino to emulate button pushes. To ensure that the head unit buttons still work in conjunction with the steering wheel buttons ...

Instructables member “Lingib” has created a awesome Arduino powered Omni Wheel CNC pen plotter, powered by an Arduino Uno and Bluetooth module allowing the system to receive commands via a ...
