ICT Revision G/6

What is the purpose of the first loop in the script?

• To turn on all the LEDs at once.

• To turn off all the LEDs at once.

• To turn on the LEDs in the first column.

• To turn off the LEDs in the first column.

What is the purpose of the second loop in the script?

• To turn on all the LEDs at once.

• To turn off all the LEDs at once.

• To turn off the LEDs in the same order they were turned on.

• To turn on the LEDs in a different order than they were turned off.

What is the purpose of the variables "ledx" and "ledy"?

• To store the current row and column of the LED being illuminated.

• To store the total number of rows and columns on the Micro:bit screen.

• To store the brightness level of the LEDs.

• To store the time delay between each LED being illuminated.

What is the purpose of the "pause" block in the script?

• To stop the program execution.

• To create a delay between each LED being illuminated.

• To reset the variables "ledx" and "ledy".

• To turn off all the LEDs.

Which of the following is NOT a correct way to turn on an LED at a specific location on the Micro:bit screen?

• plot(x, y)

• set led(x, y)

• light(x, y)

• turn on led(x, y)

What is the maximum number of LEDs that can be illuminated on the Micro:bit screen at the same time?

• 5

• 10

• 25

• 50

What is the purpose of the "forever" loop in the script?

• To repeat the LED illumination process continuously.

• To limit the number of times the LEDs are illuminated.

• To create a random pattern of LED illumination.

• To turn off all the LEDs after a certain amount of time.

How can you modify the script to change the speed at which the LEDs are illuminated?

• By changing the values of the variables "ledx" and "ledy".

• By changing the number of times the loops are repeated.

• By changing the time delay in the "pause" block.

• By changing the order in which the LEDs are illuminated.

What is the purpose of the "for" loop in the script?

• To repeat a block of code a specific number of times.

• To create a random pattern of LED illumination.

• To turn off all the LEDs after a certain amount of time.

• To create a delay between each LED being illuminated.

What is the name of the programming language used to program the Micro:bit?

• Python

• C++

• javaScript

• MakeCode
