Symbiotic Readings

4 piezos outputting information gathered from temperature, soil moisture, light and electromagnetic frequency readings on an arduino board, whilst I open the window (it's snowing outside), water the plant containing the soil moisture sensor, cover it's light sensor a bit, put my finger on the heat sensor, and at some points, hold the wire that detects electromagnetic frequency. 

Here is what it does so far: 

It works out what to play (so far only a choice between EMF based chirping and the little outbursts of song). 

It then collects 100 samples in the case of the EMF readings, or 25 in the case of the EMF+humidity duet-pulse which you hear all the way through it. Temperature is used mostly to calculate tempo.
