Built in images

The BBC Microbit has images saved on it. To access these images you have to use the correct syntax e.g. Image.HEART. Below is the code to display an image and a list of all the built in images (use the code below but change the image):

Image.HEART
Image.HEART_SMALL
Image.HAPPY
Image.SMILE
Image.SAD
Image.CONFUSED
Image.ANGRY
Image.ASLEEP
Image.SURPRISED
Image.SILLY
Image.FABULOUS
Image.MEH
Image.YES
Image.NO
Image.TRIANGLE
Image.TRIANGLE_LEFT
Image.CHESSBOARD
Image.DIAMOND
Image.DIAMOND_SMALL
Image.SQUARE
Image.SQUARE_SMALL
Image.RABBIT

Image.MUSIC_CROTCHET
Image.MUSIC_QUAVER
Image.MUSIC_QUAVERS
Image.PITCHFORK

Image.CLOCK12, Image.CLOCK11, Image.CLOCK10, Image.CLOCK9, Image.CLOCK8, Image.CLOCK7, Image.CLOCK6, Image.CLOCK5, Image.CLOCK4, Image.CLOCK3, Image.CLOCK2, Image.CLOCK1
Image.ARROW_N, Image.ARROW_NE, Image.ARROW_E, Image.ARROW_SE, Image.ARROW_S, Image.ARROW_SW, Image.ARROW_W, Image.ARROW_NW

Coding the Microbit buttons

Use the following code and see what happens

Change the images using the built in images

Random

Dice task:
When the microbit is shaken, it should display spots like a dice.
It should randomly display 1 spot or 2 spots (all the way to 6) like a dice.

Use and tweak the "Random code" from here

Use and tweak the "Image" code from here

hint:
random.randint(1,6)
This line of code generates a random integer between 1 and 6

Answer

from microbit import *
import random

while True:
    display.show(Image.HAPPY)
    if accelerometer.was_gesture('shake'):
        display.clear()
        sleep(1000)
        answer = random.randint(1,6)
        
        if answer == 1:
            one = Image("00000:00000:00900:00000:00000")
            display.show(one)
            sleep(1000)
            
        elif answer == 2:
            two = Image("00000:00090:00000:09000:00000")
            display.show(two)
            sleep(1000)
            
        elif answer == 3:
            three = Image("00009:00000:00900:00000:90000")
            display.show(three)
            sleep(1000)
        
        elif answer == 4:
            four = Image("00000:09090:00000:09090:00000")
            display.show(four)  
            sleep(1000)

        elif answer == 5:
            five = Image("00000:09090:00900:09090:00000")
            display.show(five)
            sleep(1000)

        elif answer == 6:
            six = Image("09090:00000:09090:00000:09090")
            display.show(six)
            sleep(1000)
        
    sleep(10)
