[Dimitri Diakopoulos] dropped into our tip line to let us know his HIDUINO project. The HIDUINO is a set of firmware for the ATmega8u2 used in the new revisions of the Arduino (Uno, and Mega2560 f… ...

The open-source nature of the project also means that you can modify and expand upon the design to suit your requirements. “TheMIDInator is a MIDI controller based on an Arduino MEGA 2560.

It interfaces as a PS2 device which makes it pretty simple to use in conjunction with the Arduino. But that’s not the only touch-enabled input device.

In the video below, Kale salvages potentiometers from an old mixer, then hooks them up to a Pro Micro. This allows the Arduino to take these 12 inputs, and output them as a USB MIDI signal.

And, through the Arduino PluggableUSB interface, you can easily make one of these doohickeys into a MIDI endpoint! It's a common enough use that there's an example for it.

The OONTZ uses a 3D printed case, a 16 button keypad, an Arduino Leonardo, a monochrome driver, and a few potentiometers. It's actually a pretty simple thing to build yourself provided you can the ...
