Using the tilt switch to turn a laser on and off

The tilt switch itself has a built in LED that can be used to indicate when the switch is on or off. The LED is controlled by connecting to another pin on the micro:bit. It doesn't need to be used. This video also displays the state of the switch on the micro:bit LED display using 1 and 0. Code below.

from microbit import *

x=0

while True:

    x = pin11.read_digital()

    display.show(str(x))

    if x == 0:

        pin12.write_digital(0)

        pin8.write_digital(0)

    else:

        pin12.write_digital(1)

        pin8.write_digital(1)

        sleep(10)
