[dorkbotpdx-blabber] Focused Workshop, 30Nov08, Making Noise with the Arduino.

[Donald Delmar Davis]

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

In particular I 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.
