night light challenges

Coding challenges for night light.

Before we get started

Complete the following guided tutorial, your code should look like this:

led.setBrightness(255)
basic.showLeds(`
    # # # # #
    # # # # #
    # # # # #
    # # # # #
    # # # # #
    `)
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 an event handler with on button pressed(B) add set brightness(0) to turn off the LEDs.

led.setBrightness(255)
basic.showLeds(`
    # # # # #
    # # # # #
    # # # # #
    # # # # #
    # # # # #
    `)
input.onButtonPressed(Button.A, () => {
    led.setBrightness(64)
})
input.onButtonPressed(Button.B, () => {
    led.setBrightness(0)
})

Challenge 2

Add an event handler with on shake to change the LED brightness back to a 255.
