im new to the world of physical computing and im just experimenting with different sensors at the moment.
Im looking through this Drum tutorial for ways to use Piezo’s as input
i have conected the +ve end of a 1.8khz piezo transducer element to the analog input 0 port on the arduino board and the -gve end to the grnd using a 10k resister and also (dangerously) tried without a resistor.
However when trying to read the input from this analog in im receiving ‘0’ (only when the Xducer is plugged in)
this is the code
Can anyone tell me why im receiving nothing but horrible 0’s?
