  • 4-Channel 5V Relay Module
    Well-built four channel relay
    Review by David
    Worked as expected. Don't forget that it's 5V so it won't work directly with those Arduinos that use 3.3V pins.

  • IS Relay Shield for Arduino
    good shield
    Review by Cristiano
    the shield was very good for the management of little load, such as motor or power relè.

  • SeeedStudio 2-Channel 315MHz Wireless Relay Switch
    Great product for low price!
    Review by Jeremie
    The information provided by the manufacturer is a bit hard to understand for a novice, which I'm not.

    Anyway, the device works great and the range is surprinsingly good.

  • DoubleSwitch Radio Controlled Relay
    Great product
    Review by Stephen
    I am using this on an RC model Tug, It works very well.
    but I wish there was an On - Off - on version available as well.

  • BattleSwitch Radio Controlled Relay - DE-01
    LED spotlight
    Review by Larry
    I needed a way to turn on a 9 LED spotlight on my
    robot.The battle switch is perfect for the job! It has a small form factor and is very easy to install in your bot.
    I will be ordering more of these because You can use them to control just about anything with your rc xtmtr.
    Thanks Robotshop!

A relay is best if you don't need to vary the speed or direction. If you do need to change the direction or speed, then you'll need a motor controller:
