This 4 Channel 5V Relay Module has the ability to switch up to four circuits using digital signals from a microcontroller. Each relay works like an SPDT Single Pole Double Throw switch and can be wired for both NO Normally Open and NC Normally Closed operation. Your robot's microcontroller can flip one of the switches by simply setting a connected digital output line high.
Each relay channel has a corresponding LED for visual feedback.
