Summary of experiments with IR beam detection.
Initial testing with Radio Shack sensors and IRremote library: http://reactivemusic.net/?p=4027
musical stairs project
Built by students at Gould Academy, Bethel, Maine 2013.
Detects movement on stairs using individual IR sensor pairs on each step. When an IR beam is broken, a note is triggered and status LED lights up. Using an Ethernet shield, the data is tracked in a feed at xively.com
