Vibration Sensor: The tube has a very weak spring and a stiff wire down the centre. When the sensor is tapped the spring moves and makes contact with the central wire. We call this module a "switch." Only the top and bottom pins connect to the switch. The "contact" will be very VERY brief and you need a circuit that is capable of detecting a short "pulse." Connect to port 5 and place active speaker in Port 6. Flick the sensor and the speaker (buzzer) will give a short chirp
