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.
