What exactly is Micro:bit?

• It is a small portable board, which can be programmed by a compute.

• It is a little cell phone.

• It is a computer game!

• It is an electronic maze.

Why we should use Micro:bit as students?

• Because it is the best electronic device that has ever been made.

• Because most electronic devices, (alarm clock, digital tv, alarm systems), use a microcontroller to operate.

• Because in that way we customize, control, and 'bring to life' digital ideas and games.

• Because Micro:bit is a robot with artificial intelligence.

Which are the labels of Large Pins in Micro:bit? (General Pins Input Output)

• The two large pins (labeled 3V and GND)

• Only the 2nd terminal (labeled 2) and 3rd terminal (labeled 3V)

• The terminal labeled 0 and the other large pin labeled GND

• The first three terminals, labeled 0, 1 and 2.

The power terminal labeled 3V can be used as an output or input? (with a voltage of 3V)

• As an output: If the micro:bit is NOT powered by USB or battery, then you can use the 3V pin, to power peripherals.

• As input: If the micro:bit is powered by USB or battery

• As an output: If the micro:bit is powered by USB or battery, then you can use the 3V pin,you can use the 3V pin as a power output to power peripherals. to power peripherals.

• As ground: to complete a circuit

Which two terminals, must never be connect together?

• The pins labeled 3V and GND are related to the board's power supply and should NEVER be connected together.

• The Large PINs should not never be connected with Power Terminals.

• You must not connect together terminals 0 and 3V

• The pins labeled 0 and 1 are the Large Pins, often called 'general purpose input and output 'and should never connect together.

Sequential structure Part 1: What appears on led screen if button A is pressed?

• Only a little dot appears at the middle of the screen

• Only a square appears at the corners of the screen

• A little square appears and dissappears after 500ms

• A square appears, then a smaller square. and finally, a dot.

Sequential structure Part 2: What appears on led screen if button B is pressed?

• Only a rhombus appears on screen

• A little smile appears on scree

• A rhombus appears, then a smile and finally a sad face.

• A rhombus appears, then a smile appears after 3 seconds and finally a sad face

When Micro:bit plays C, D, E tone?

• When button A is pressed and light level is >100

• When button A is pressed and light level <100

• When button A is pressed and light level=100

• When button B is pressed

Look at the following code, regarding Pin 1

• Micro:bit reproduces 2 musical notes, if pin1 is pressed for 2 seconds.

• Micro:bit reproduces 2 musical notes, if pin1 is pressed, forever.

• Micro:bit reproduces 4 musical notes, if pin1 is pressed.

• Micro:bit reproduces 2 musical notes, if pin2 is pressed

Micro:bit gets as an input, sound levels from the environment and...

• when variable 'sound level' is equal to the maximum level of sound, then show on Micro:bit led screen, the average of sound level values

• when variable 'sound level' is greater to the present level of sound (named as 'max sound), then show on led screen the maximum value of sound.

• when variable 'sound level' is equal to the maximum level of sound, then Micro:bit reproduces a melody

• when variable 'sound level' is equal to the minimum level of sound, then show on led screen this value
