Control of Ableton effects using Arduinos, sensors and Pure Data

I hooked up a variety of sensors and switches to an arduino and sent the data into a Pure Data patch. The messages are processed and sent into Ableton and a song that I am currently composing and producing. I am able to turn on and off effects using the switches and modulate filters using force sensors and potentiometers.
