Purpose of this tutorial:
In this tutorial we will control the ignition of an RGB LED via the two buttons A and B of the micro:bit card:
1- When we press the button A, the LED lights up in red.
2- When you press the B button, the LED lights up green.
3- When you press the 2 buttons A and B at the same time, the LED lights up blue.
Assembly Connect:
- Pin Po from the Micro:bit board to pin (R) for the red color of the RGB LED module
- Pin P1 from the Micro:bit board to pin (G) for the green color of the RGB LED module
- Pin P2 from the Micro:bit board to pin (B) for the blue color of the RGB LED module
- the GND pin of the micro:bit to pin (GND) board of the RGB LED module
Required components
- Micro:bit led RGB 3 board
- Resistors of 22O Ω micro:bit GPIO Expansion Board
- Connecting wires
