This neat little gadget can do things like generate PWM or DAC signals, read serial output of your microcontroller project, as well as several other useful functions. The design of the Little Helper was inspired by the iPod interface. It’s custom touch wheel allows for fast one-handed operation.
The project is open source. You can find the code on Github.

There is a bit of a write up on the project over on Hackaday.
