My vibration sensor came with the Intermediate Kit, I'm following the tutorial on it and my sensor constantly registering and output of 1 (via serial monitor), even though nothing is moving it (on which it should register 0) and lay flat on my workbench...is there a way to test the functionality of the sensor (or its sensitivity)...thanks...
