Turn on LEDs by remote control with Micro:bit

Purpose of this project:

In this project we will remotely turn on LEDs by an infrared remote control:

• If you press the button 1 on the remote control, the green LED will turn on or off.
• If you press button 2 on the remote control, the orange LED will turn on or off.
• If you press the 3 button on the remote control, the red LED will turn on or off.

Necessary components

• micro:bit
• 1 LED green
• 1 LED yellow
• 1 LED red
• micro:bit GPIO Expansion Board
• infrared sensor
• infrared remote control
• wires connection
• test plate

Mounting

To complete the assembly, you can connect the green LED to pin P0 , the yellow LED to pin P1 and the red LED to pin P2 of the micro:bit board.

For the IR sensor you can connect:

• Pin OUT to pin P4 of Micro:bit
• Pin (+) to pin 3.3V of Micro:bit
• Pin GND to GND of Micro:bit

The mounting methods are numerous and here are some examples:
