6. For loops with range Code Ordering
6.1. Question 1
A student is coding an automated greenhouse plant watering system.
Rearrange the lines below to create a loop that runs exactly 3 times to show an indicator image on the micro:bit display panel for each watering cycle.
Drag and drop lines into the correct order and click to adjust indentation:
☰
for pump_pulse in range(3):
☰
display.show(Image.HAPPY)
☰
sleep(1000)
☰
from microbit import *
☰
6.2. Question 2
Put the code snippets in order to build a lighthouse safety beacon.
The program must flash an alert symbol (“X”) a total of 4 times.
Drag and drop lines into the correct order and click to adjust indentation:
☰
for flash_count in range(4):
☰
sleep(200)
☰
display.clear()
☰
☰
display.show("X")
☰
from microbit import *
☰
sleep(200)
6.3. Question 3
Arrange the lines of code to create a rocket launch systems checker.
The loop should step a counter variable through its default sequence starting from 0, stopping automatically just before it hits 5, to scroll each checkpoint number.
Drag and drop lines into the correct order and click to adjust indentation:
☰
☰
display.scroll(check_id)
☰
sleep(200)
☰
for check_id in range(5):
☰
from microbit import *
6.4. Question 4
A student wants to flash a digital binary metronome signal.
Order the lines below to create a loop that steps a variable through the numbers 0 and 1 only, showing each digit on the screen.
Drag and drop lines into the correct order and click to adjust indentation:
☰
for beat in range(2):
☰
☰
display.show(beat)
☰
from microbit import *
☰
sleep(500)
☰
while True:
6.5. Question 5
Rearrange the code segments below to create a simple step-multiplier calculator for a fitness tracker.
The loop should run 3 times (generating values 0, 1, and 2), multiply each value by 10, and scroll the calculated results.
Drag and drop lines into the correct order and click to adjust indentation:
☰
total_steps = step_factor * 10
☰
☰
from microbit import *
☰
display.scroll(total_steps)
☰
sleep(1000)
☰
for step_factor in range(3):
