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

Wanna dorkboard but afraid of surface mount?

Brian Riley at Wulfden will sell you a stripped down dorkboard kit with the reset pullup resister and the programming jumper ALREADY SOLDERED! and for another 6 bucks you can build a nifty flashlight!

Schematic for the flashlight kit.

Using the new features of arduino 12.

There is much that is new in the new arduino. Most of it in the user libraries and all of it good. My favorite is the addition of the ability to specify a different programmer as long as its avrdude approved.

If you select the boards on my Arduino setup it will look very different than the stock Arduino.

As it gets dark I find myself needing to get the blinking lights working on my bycycle. I am also reminded of the ever present need to find space where you don't have to breath what you work with. Three days after casting the first set of lights the apartment still reeks.

I needed to test the new sensors I am putting on the Rapha stationary bike race controller so I built a 4 bike race "emulator". As you can hear in the video attached the motor controller test program sounds very blade runnery.

And then there are those days when I don't care.
