Relay (Grove 103020005) component

The Relay is a digital normally open switch capable of switching much higher voltages and currents than your normal Microcontroller outputs. When set to HIGH, the LED will light up and the relay will close allowing current to flow. The peak voltage capability is 250V at 10 amps. Simulated component, green indiacator is on when the relay is active.
