Update - Sounds and Sound Interaction

We've combined the results of last time's competition, taking ideas from the other teams into one idea.

1. Approaching a Module. If someone is near a module, or in between two, a range finder will detect them and activate a chime sound to indicate that the module can be interacted with and involves sound. Similarly, if the range finder is activated but none of the sensors have been activated in a certain amount of time the chime sound will again play, beckoning people to come interact with it.

2. Under the arch. We take Team 5's concept of combining range finders with IR pairs in order to measure the height at which the IR beam was broken. One instrument will have three pitches or note combinations staggered along the height of the angle under the arch. If the beam is broken higher up, the higher note combination will be played and vice versa.

3. Sensor Interaction. As we described last time, multiple sensor activation is rewarded, encouraging community participation. The sensors will represent one of 4-5 instruments. When one is activated alone, it will play a short rhythm or beat. If 2 are activated, a short song will play involving the instruments of those two sensors. As more sensors are activated at the same time, a richer, more complicated song will play. It becomes a challenge for interactors to find the hidden songs in the module (3-4 perhaps). In order to allow a person interacting alone to find the songs, there will be a small time window (perhaps 1-3 seconds) for other sensors to be activated once one sensor is activated and then trigger a song.

*UPDATE*
After looking at the physical construction of the modules, it seems to make more sense to simply put an IR pair across the underside. When the IR beam is broken, a sound should be triggered.
