LED Light Control with Micro:bit

This video tutorial demonstrates how to write code to make an LED light flash using a micro:bit. The LED is connected to pin 1 and GND, and the code is written using a forever block. The tutorial explains how to use digital write commands to turn the LED on and off with pauses in between, creating a flashing effect. The video also shows how the code works in an emulator, where pin 1 turns orange to indicate the LED's state.

What is the purpose of connecting the GND alligator clip to the short wire of the LED?

• To provide power to the LED

• To increase the brightness of the LED

• To complete the circuit and allow current flow

• To change the color of the LED

Why is pin 0 reserved for speakers in the code?

• To avoid interference with the LED

• To keep it available for audio output

• Because pin 0 is not functional

• To use it for another LED

What does setting 'digital write pin 1 to 1' accomplish in the code?

• It turns the LED off

• It increases the LED brightness

• It turns the LED on

• It changes the LED color

How long does the LED stay on when a pause of 500 milliseconds is added?

• 1 second

• 250 milliseconds

• 500 milliseconds

• 2 seconds

What is the effect of setting 'digital write pin 1 to 0' in the code?

• It turns the LED on

• It changes the LED color

• It increases the LED brightness

• It turns the LED off

What is the purpose of the forever block in the code?

• To change the LED color

• To stop the code after a few cycles

• To repeat the code indefinitely

• To run the code once

What visual feedback does the emulator provide for the LED?

• It turns pin 1 orange on and off

• It increases the brightness

• It displays a color change

• It shows a blinking LED

What is the main outcome of running the complete code?

• The LED changes color

• The LED turns off permanently

• The LED flashes on and off

• The LED stays on continuously
