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).

Learn how to use the photoresistor (RP) of Snap Circuits as a light sensor input for the micro:bit.
