A Relay Module that can easily be controlled by a Bit Board, Robotics Board, or MicroBit.
A Relay Module allows a microcontroller, such as a MicroBit, to turn on or off a 'dumb' component. Think of it as a programmable DC switch. Typically these are used to turn on or off high amperage draw components, such as a motor or water pump, since such components will destroy a microcontroller if hooked up directly. We use this module in projects such as our Bubble Blower or Automatic Plant Watering System.
To use this component, just connect it to your micro controller of choice with a ribbon cable. Then connect your motor (or other component) along with a power source (such as a 2AA battery holder or 9V plug) to the screw terminal side. You're now ready to turn things on and off.
For example code, please reference this guide. For example projects please look around our Project Database.
