Making Noise with the Arduino November 30, 2008

As a part of the ongoing Arduino Cult Induction workshop series, this month we will be focusing on sound.

In particular Don will be going over creating sound using the Arduino's built in Pulse Width Modulation (PWM) and Direct Digital Synthesis using resistive ladders. We will investigate using the Piezo element
as both a simple speaker and an input trigger. We will review the Musical Instrument Digital Interface (MIDI) from a hardware and software perspective, and look at a couple of useful integrated circuits (the lm324 and the lm368).

The workshop will cost $25 and participants will recieve a complete midi interface board for the dorkboard/arduino and a piezo element which will be used to create a midi drum trigger. Participants will also take with them parts for an r2r ladder, an op amp and an audio amp capable of driving small speakers or headphones.

Participants should leave the workshop with a better understanding of
how micro-controllers such as the Arduino can be used to create and control sound, they should have built at least one working musical controller and they should have the foundations for several sound related projects.

Please bring your dorkboard, rbba, or other arduino compatible board, a soldering iron or breadboard, and a laptop.
The workshop will be held at PNCA (NW 12th and Johnson) in room 205 from 1-5pm on Sunday, November 30.
