Step 1: Make it
What is it?
Finding hard to decide or agree on what to do? Let this micro:bit program choose for you!
These two videos show you what you'll make and how to code it:
How it works
- Pressing button A makes your micro:bit choose a random number between 1 and 6.
- It stores the number in a variable called random_number.
- The program tests the random number using selection. Depending on the number, different activities are shown.
- It doesn't specifically test if the random number is 6 - why is this?
What you need
- micro:bit (or MakeCode simulator)
- MakeCode editor
- battery pack (optional)
Step 2: Code it
1from microbit import * 2import random 3 4while True: 5 if button_a.is_pressed(): 6 random_number = random.randint(1, 6) 7 if random_number == 1: 8 display.scroll('PE with Joe') 9 elif random_number == 2: 10 display.scroll('watch a movie') 11 elif random_number == 3: 12 display.scroll('play a board game') 13 elif random_number == 4: 14 display.scroll('tidy our rooms') 15 elif random_number == 5: 16 display.scroll('play a card game') 17 else: 18 display.scroll('learn a song')
Step 3: Improve it
- Customise it by putting your own activities in the code.
- Add more activities.
- How could you make it less likely that it tells you to tidy your room?
