Here’s my code for the arduino sketch and pure data so far. Works ok in really quiet environments if you play the song a two or three times. Would like to filter the data better to make it more accurate and perform better in environments with regular low-level noises going on. Also does anyone knows of a small lock that can be used with arduino?

The simplest interaction between the arduino and pure data is by using the comport object in pure data and sending data to it using the Arduino’s Serial object. Below is an illustration of two way communication between pure data and the arduino.  On the right the comport object receives values as bytes and puts them on the first vslider. The values from the second slider are sent to the comport. On the left you can see the code for the arduino. The arduino reads the potentiometer and if the value has changed writes the value (scaled to fit in a byte) to the serial port. Then it checks to see if a value has been sent to it and if its different from the last value it sets the led pins pwm value accordingly.

My idea is still tentative, but I really want to take advantage of the leap motion sensors input capabilities.

For now, I was thinking of hooking up each sensor to a separate servo motor with something interesting attached to each.

If I can’t think of anything meaningful to append to the servos, I will make the outputs trigger some kind of sample via MIDI.

If I go the MIDI route, I will try to use the gesture library to save patterns and do something interesting with that.

Here is a leap motion promo video for anybody interested: https://www.youtube.com/watch?v=_d6KuiuteIA

Does anyone have any extra fiber optic filaments I could play with?

I was curious what LEDs were indicating and this answered it, plus links to many more topics.
