Originally we were going to be switching channels of music on and off using manual switches under custom made footpads - fiddly!! After a workshop (An Introduction to Arduino) we have decided to change the switches to infrared sensors. When the infrared beam is broken this will send a signal to switch the music on or off however we will also be able to get the distance away from the sensor that the beam was broken. If we have time we can then give another element of control to the users.
