The Parts

  • Arduino Fio
  • 3.3v LiPo Battery
  • RN-42 HID BT
  • Tilt-Ball Switch
  • Orange LED
  • 20k Ohm Resistor

The Process

The overall process of working with the Fio was interesting. It needs to be programmed via FTDI breakout, so uploading with the correct headers means it needs to be held against itself while uploading. ALSO the RN-42 was a cheaper route than the XBEEs but we had issues getting to the point where wireless communication was taking place… This link spoke directly to our issues with RN but did not provide us with an answer as to how to reconfigure baud rate on the latest version of Arduino… lumos3lumos2

Testing the tilt with the LED. This circuit wasn’t working.

Simon + EL Strap

Simon primarily functions via the GinSing shield, calling it’s own library allowing manipulation of multiple oscillator banks. The largest challenge so far is the fact that ones synthesis is established, it must run through the code once in order to read new values. Although this provides a clean timing and tempo to Simon’s expression, it does limit the code as it is flowing. My current goal is to instantiate separate synthesis functions that can be called as opposed to using void loop.

Also a part of Simon’s existence is his Strap. Here’s a video of me fooling around with it…

As you can see in the code, I am currently only using one oscillator bank, and hopefully I will be able to incorporate different forms of synthesis and map them to the push buttons on the front. Also I hope to make the lever switch on the front a ‘mode’ selection switch.

As of right now these are the current parts (7805 and 7 digit numeric display not included yet):

  • GinSing Synthesizer Shield
  • Arduino Uno
  • 2 10k ohm Potentiometers
  • 3 yellow push buttons
  • 1 large yellow LED
  • 1/4 inch audio jack (male and female)
  • 10k ohm slide variable resistor
  • lever switch
