Science Museum - Collider

As part of the Science Museum’s “Collider” exhibition celebrating the LHC at Cern and the work of Professor Higgs I was asked to create this small sound installation. The exhibition itself was an unusual mix of audio-visual content arranged in a mock-up of part of the LHC building through which visitors moved. In order to minimise cross-talk between the radio installation and the various other audio pieces it was specified that the radio be activated by human presence.

I created an Arduino program that used a state machine implementation to order the playing, pausing and re-starting of the audio piece according to the various states of human absence, presence, dwell and concurrency measured by the ultrasonic sensor.
