TinkerKit Tilt Sensor module can detect when it is at an angle. This module contains two contacts and a small metal ball. When the sensor is in its upright position, the ball bridges the two contacts, completing the circuit. When the board is tilted, the ball moves, and the circuit opens. When upright, the module outputs 5V and when it is tilted, it outputs 0V. When connected to an input on the Arduino using the TinkerKit Shield, you can expect to read a value of 1023 when in its upright position and 0 when it is titled.
This module is sensor. The connector is an output, which must be connected to one of the input connectors on the TinkerKit Shield.
