LEGO® Mindstorms® Spike Hub and the Hub Buttons

A Python snippet utilizing the LEGO Spike buttons, MicroPython, and the is_pressed() and is_released() commands.

Sample Code

from mindstorms import MSHub
from mindstorms.control import wait_for_seconds

hub = MSHub()

while True:

    if hub.left_button.is_pressed() and hub.right_button.is_pressed():

        break

    elif hub.left_button.is_pressed():

        hub.speaker.start_beep(50)
        hub.status_light.on('violet')
        hub.light_matrix.show_image('ARROW_W')

        hub.left_button.wait_until_released()

    elif hub.right_button.is_pressed():

        hub.speaker.start_beep(70)
        hub.status_light.on('green') 
        hub.light_matrix.show_image('ARROW_E')

        hub.right_button.wait_until_released()

    hub.speaker.stop()
    hub.status_light.off()
    hub.light_matrix.off()

    wait_for_seconds(1)

    hub.speaker.beep(90)

hub.speaker.beep()
