set brightness challenges

These challenges will allow you to change the brightness of the micro:bit. docs

Challenge 0

This tutorial will show you how to set the brightness on the micro:bit.

led.setBrightness(255)
led.plotAll()
input.onButtonPressed(Button.A, () => {
    led.setBrightness(64)
})

Challenge 1

What if we want to turn off all the LEDs? Let's do this by setting the brightness to 0 when button B is pressed. Add a condition for input->on button pressed("B").

led.setBrightness(255)
led.plotAll()
input.onButtonPressed(Button.A, () => {
    led.setBrightness(64)
})
input.onButtonPressed(Button.B, () => {
}) // ***

Challenge 2

Inside of the condition input->on button pressed("B"), add led->set brightness(0) to turn off the LEDs.

led.setBrightness(255)
led.plotAll()
input.onButtonPressed(Button.A, () => {
    led.setBrightness(64)
})
input.onButtonPressed(Button.B, () => {
    led.setBrightness(0) // ***
})

Challenge 3

Now, in the condition input->on button pressed("B"), add basic->pause(1000) and then set the brightness to a new value!

Run your script to see the LEDs change brightness.
