Your Arduino will be expanded by 4 relays!
The Arduino 4 Relays Shield allows your Arduino to drive high power loads.
Arduino® Shield 4 Relays
The Arduino 4 Relays Shield is a solution for operating high power loads that cannot be controlled via Arduino's digital IOs due to the controller's current and voltage limitations. The shield has four relays, each relay has two polar changeover contacts (NO and NC) to increase the current limit of each output, the two changeover contacts were connected in parallel. Four LEDs indicate the on/off status of each relay.
