ive received an arduino decimilia in the post.
what i am trying to do is to recreate the piezo knock example shown at http://webzone.k3.mah.se/projects/arduino-workshop/projects/arduino_meets_processing/instructions/piezo.html
So far just using the arduino example code (not processing yet)
I have the piezos and 1k resistors but after compiling & uploading to the board I look at the serial monitor and recieve A LOT of 'knocks' without actually touching the piezo.
I know the equipment is fine because i have successfully used it to output a musical riff through the piezo.
all advice much appreciated!!
