Microbit and KY-034 7 color flashing LED

In this article, we connect a KY-034 7 color flashing LED to our Microbit – we will use Makecode and show the JaavScript and Python output as well

If the  KY-034 7 color flashing LED module is supplied with voltage, a color sequence is automatically emitted by the LED. The LED has 7 different colors and thus also all resulting mixed colors.

Working voltage 3V — 5V DC
LED model YB-3120B4PnYG-PM
LED type 5mm round head

Parts Required

All of these are from the Microsoft Makecode site

MakeCode

Python

def on_button_pressed_a():
    pins.digital_write_pin(DigitalPin.P0, 0)
input.on_button_pressed(Button.A, on_button_pressed_a)

def on_button_pressed_b():
    pins.digital_write_pin(DigitalPin.P0, 1)
input.on_button_pressed(Button.B, on_button_pressed_b)

 

JavaScript

input.onButtonPressed(Button.A, function () {
    pins.digitalWritePin(DigitalPin.P0, 0)
})
input.onButtonPressed(Button.B, function () {
    pins.digitalWritePin(DigitalPin.P0, 1)
})
