I want to thank SparkFun for selecting me as a Hacker-in-residence, even though I couldn’t get out to Boulder I am very excited to be working with the SparkFun team. I will use this post to keep track of the status of my project. You can read more about it on SparkFun.
This project will be an Arduino controlled midi instrument, with IR sensors as input and a Midi shield to talk to a midi module. The IR sensors and Arduino will be mounted on something like a hula-hoop, and people can stand around it and put their hands in the IR beam to generate sounds. Hopefully 4-8 people working together will be able to create some interesting music.
The code for this project is on github.
Today (July 3 2014) I finally got my package from SparkFun, at first I was surprised by the size and weight of the box, I wasn’t sure what to expect. When I opened it all I saw was the recyclable packing material, after I pealed away a layer of packing material I finally got to the electronics.
I dug around a bit more and I found out why the box was so big, they decided to include some presents:
They added some awesome SparkFun Engineering Department beer mugs, the mugs appear to be half liter, and I can’t wait to use them.
Making a sound
After some struggle with the midi module (Yamaha AN200 in case you care) I finally got the thing to make a sound, I was having troubles at first because I didn’t realize that when the arduino rebooted the AN200 also needed a reboot; otherwise it would not take input from the arduino.
Now that I have that all sorted out I have figured out a few ways to modulate the sound based on input from the IR sensor, and I have made a small video of it in action with just one sensor hooked up.
Stay tuned for more updates.
