MonkMakes Relay for micro:bit Raspberry Pi Zero 2 you will need to purchaseThe MonkMakes Relay for micro: bit is a solid state (no moving parts) relay that allows an output of a micro: bit to turn things on and off. This relay can be used to switch low voltage devices such as light bulbs, a motor, a small heating element or even a string of 12V LED lighting. The voltage needs to be kept under 16V, but the relay will automatically protect itself against too much current.
