Automatic lighting system with Micro:bit

Purpose of this project:

In this project an automatic lighting system with Micro:bit will be realized. It consists of turning on an LED lamp when the room becomes dark and turning it off otherwise.. It mainly uses a light sensor KY-018.

Required components

• Micro:bit board
• light sensor KY-018
• 1 resistance 220Ω
• 1 red LED
• connecting wires
• GPIO expansion board

Mounting

To perform the assembly:

• the red LED terminal (+) can be connected to pin P0 of the Micro:bit
• the red LED terminal (-) to pin GND of the Micro:bit
• the DO pin of the light sensor to pin P1 of the Micro:bit board.
• the VCC pin of the light sensor at the 3.3V pin of the Micro:bit board.
• GND pin of light sensor to GND pin of Micro:bit board .

The mounting methods are numerous and here are some examples:
