Pure DatrocessorduinoMOS

This is a really fun way of learning how to integrate software based interfaces, custom code, and physical hardware through music. A crash course in building connections between Pure Data or Processing and DIY CMOS circuits using Arduino. 

Don’t worry if you’re not a seasoned expert in any of these areas. Examples will be provided and explained along with brief introductions to the systems/environments and how to explore them further on your own. This workshop is part of the Dark Circuits Festival 2014.

There are three parts to this workshop:

• CMOS Digital Logic – We will begin with a simple CMOS oscillator circuit and expand it to be controlled using logic level signals. Expect to learn a little bit about basic binary math, counting, digital addressing, and multiplexing. From simple concepts come powerful tools. The expanded oscillator we’ll create happens to be a really noisy and flexible one.
• Controlling CMOS with Arduino – After playing the oscillator manually using jumper wires, we’ll switch gears and setup our Arduinos to connect with the CMOS. We’ll review code examples that will allow us to create pre-programmed and/or generative musical sequences by directly controlling our oscillator with the Arduino.
• Controlling Arduino over serial (via Processing and/or PureData) – Once we’ve established a connection between the CMOS and Arduino, we’ll get started on building a bridge between the interactive environments of Processing and Pure Data and Arduino via serial communication protocols. Whether by code or by patching environment, you can build out custom interfaces to issue commands to the Arduino over serial and cause your CMOS oscillator module to do some freaky things.
