the guy is using Arduino, well, you should use a resistance of 1 kohm,
the schedule is the same as I show you, you must use the red wire inside
and black outside your "penny" ... resistance to the ground will be used to enter the analog, as a ldr, is the same pattern ... You can check it on the web ...</span><span style="background-color: rgb(255, 255, 255);"> </span><a href="http://webzone.k3.mah.se/projects/arduino-workshop/projects/arduino_meets_processing/instructions/ldr.html">http://webzone.k3.mah.se/projects/arduino-workshop/projects/arduino_meets_processing/instructions/ldr.html</a><span style="background-color: rgb(255, 255, 255);"> , also you would need a flex sensor... more stability and non erratic performance...</span><br>

Hi <br><br>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.<br>
Anybody knows a efficient way to do this? how can i improve the accuracy?<br><br>Thanks ¡¡<br>
