    Time to step up the voltage with this Arduino Relay Board. The Arduino platform is a great way to control lights, buzzers, displays and more - but what if you have a device that doesn't run on the Arduino's native 5 volts? One simple way to do it is to use the RobotGeek Relay. This little relay board will use a signal from a 5v microcontroller to make a mechanical connection. This connection is physically seprated from the arduino, meaning you can connect devices that have different voltages up to it! These relays can handle up to 5 amps at 250 volts

    This Arduino Relay board has the standard RobotGeek three pin connection so it plugs right into the RobotGeek Sensor Shield to get you up and running immediatly.

    The RobotGeek Relay can be run in 2 ways. Connect your external device through the NO(Normally Open) terminal, and the electro-mechanical connection will be made whenever you send a 5v signal to the relay board. Connect your external device through the NC(Normally Closed) and the external device will be normally on, turning off whenever the relay receives a signal.

    As with all RobotGeek sensors, the hole mounting pattern is on a 1x1 CM grid so they easily mount to the RobotGeek Workbenches or any other RobotGeek kit.

    Don't forget to pick up RobotGeek Sensor Cables if you need some!
