After our meeting with Mikael last Thursday, we decided it would be best to use Piezo transducers rather than force sensitive resistors. Firstly, the ones that Mikael had were wire-free, complicated to connect to an arduino. Secondly Marc McLoughlin used piezos on his bodybeats project last year and he may be helpful if we encounter difficulties. Also, after testing the Piezos on an oscilliscope we feel they should be more than sufficient for the sensitivity we are looking for.
And onwards we went. On connecting to the Arduino I realised that a threshold of 250 was good to detect sufficient force on the sensor. On successfully connecting numerous sensors, we began looking at how we could interface this with PD to output synthesized sounds. To create the sounds we needed to use the modal partial frequencies of our 2 octaves.
One resource that can give us information on this is Rossings 'The Science of Sound'.
Next: compose and output sounds using Pure Data
PDuino firmware downloaded and installed, the Simple Message System will be used to read the arduino
