The MonkMakes Relay for the BBC microbit is a solid state relay (no moving parts) that allows the output of a micro:bit to turn things on and off A micro:bit can directly turn on and off an LED, but anything more powerful requires something like a relay or transistor. Using a transistor to turn something on and off requires a common ground connection to the micro:bit and knowledge of electronics, which you or your students may not be ready for. The MonkMakes Relay for micro:bit is much easier to use, as it works like a simple switch controlled by the micro:bit This relay can be used to switch low voltage devices such as light bulbs, a motor, a small heating element or even a set of 12V LED lights. The voltage must be kept below 16V, but the relay will automatically protect itself from overcurrent Χαρακτηριστικά: Solid state relay (no moving parts) Resettable “multi-fuse” for overcurrent protection Maximum current 2A Maximum voltage 16V Built-in active LED power indicator
