An Arduino Nano is charged with running the show, capturing audio via its analog-to-digital converter. A sensitivity pot enables the input level to be set appropriately.

I went a step further and bought 20 extension cables from China for ~$2 each. I snipped off the “wrong” end of the cable with about six inches of wire (in case I wanted to make a control someday).

It is equipped with 32 Inputs (16 x digital 4-30V, 8 x analog 0-10V, 4 x analog 0-5V, 4 x analog 4-20mA) and 20 Outputs (8 x relay 250V/5A, 2 x open-collector 30V/1A, 8 x analog 0-10V) and offers ...

If you are looking for a project to keep you busy this weekend you might be interested in a new MIDI fader unit which is being created using a little 3D printing and Arduino programming.

Arduino has announced four new Nano microcontroller-based boards that will be available for developers and makers in late July. ... Arduino notes it only supports 3.3V input and outputs ...
