Hi
I need to use a piezo to trigger a bang in a pd patch but i am having some problem of inestability. I use the piezo like an analog input to arduino board, then comunicate with pduino ( firmata 2.1.) Once in the patch i use an arduino object to detect the signal from piezo and a threshold object to trigger a bang when the value of the signal goes up the threshold. The problem is the acuraccy of the sistem, because is really unprecise, sometimes trigger doestn work and some times trigger more bangs than hits to the piezzo. Anybody knows a efficient way to do this? how can i improve the accuracy?
Thanks ¡¡
