The Pushbutton Module is possibly the simplest sensor available. It detects when a person or an object presses its circular cap.

Output: This module outputs 5 V when the button is pressed and 0 V when released. Pressing the button closes the circuit. When connected to an input on the Arduino using the TinkerKit Shield, you can expect a value of 1023 while the button is pressed and 0 when released.

Module description: This module features a 12 mm push button, the standard TinkerKit 3-pin connector, a green LED that signals that the module is correctly powered, and a yellow LED that is lit only when the button is pressed.

This module is a SENSOR. The connector is an OUTPUT which must be connected to one of the INPUT connectors on the TinkerKit Shield.
