Am getting strange results with the Grove Piezo Sensor. It is giving high readings all the time (value = 1024), using the grove_pizeo_vibration_sensor.py script . Tried with 2 different sensors. Still gives high readings. It randomly outputs 0 readings every now and then.
Have tried shaking and moving the sensor, and the reading generally stay at 1024 the whole time, even when I stop moving the sensor.
Any ideas why?
