In this quick and easy project, you build a micro:bit moisture sensor

Learn how to use the infrared receiver (U24) of Snap Circuits to detect input from remote controls with the micro:bit.

Learn how to program the micro:bit to turn the DC Motor (M1) of Snap Circuits on and off with the help of the NPN Transistor (Q2).

Learn how to power the micro:bit from the battery holder of Snap Circuits.

Learn how to connect a Snap Circuits LED to the snap:bit and control it with the micro:bit.

Learn how to play sounds and music from the BBC micro:bit through the Whistle Chip (WC) of Snap Circuits.

Learn how to play sounds and music from the BBC micro:bit through the Speaker of Snap Circuits.

Learn how to program the micro:bit to turn the Lamp (L1) of Snap Circuits on and off with the help of the NPN Transistor (Q2).
