Phase 2: Getting the sound to work...

This week we hashed out the digital interaction and got a sample working on our newly soldered wave shield-arduino sandwich. The soldering could be a bit tricky, but was overall a lot of fun. As far as programming, the wave shied site was incredibly helpful.


The photo above if from an initial try, but as of now we can activate two photoresistors independently. If - looking at the diagram below - you activate only photoresistor A, it will place its wav file. If you activate only photoresistor B, it will place its wav file. If both are activated together, the system will play and loop a wav file that is the combination of A and B's sounds. For example, if A is a trumpet melody and B is a drum beat, A-B will a trumpet-drum beat loop.
We are estimating approximately 8 photoresistors per module, so there will have to be a wav file for every distinct combination of 8.


Some possible issues we came across while testing:

• Cloudy Days. We noticed that the numbers output by the photoresistor changed a great deal when we closed the blinds, or the sun went away. This affected our parameters for when the sound should go off.
• Range of Photoresistors. We aren't sure of the maximum distance that will set off the resistors. Would a shadow from a few feet away do it? This might not be a problem, but something to investigate.
