Eurorack and Arduino. What common may be between a huge analogue rack and a brains for a toy robot? Perhaps it is openness of the both platforms and broad variety of existing solutions based on them. Nowadays it is not something outstanding to use a digital controller inside analog module, but Arduino also is respected for its simple and user-friendly development tools, allowing to create a device doing random tasks for minimum time and money. A couple of years ago Arduino chips had took their place in Eurorack modules. 4ms, Flame use AVR controllers in their products and Soundmachines specifically used Arduino to develop their Robotto and had published an SDK for it.
And now appeared modules that are intended to be programmed by owners. The first one was utility-module Expert Sleepers Disting ($175), based on PIC32MX uC, then Circuit Abbey Euro-Duino ($145), based on Arduino as it comes from the name. The price for the DIY kit of this module is just $95 and it has lots of fun within! So, let’s take a closer look at the module.
