Buttons are important for Arduino interactive projects. Grove - Button is a momentary push button. It contains one independent "momentary on/off" button. “Momentary” means that the button rebounds on its own after it is released. The button outputs a HIGH signal when pressed, and LOW when released. The Sig marked on silk layer stands for a signal while NC stands for not used at all. 

Grove connectors also help you paring the button by the way of only plug and play. If you wish to ON/OFF a circuit by pressing a button-down instead of flipping it, the Grove – Button is for you!
