Micro:Bit Quiz Unit 3

What are the gold circles at the bottom of the micro:bit called?

• Rings

• Pins

• Volts

• Activators

How do you activate a Pin Press Event?

• Press A and B at the same time

• Zap the micro:bit with an electric shock

• Touch the pin and Ground at the same time

• Tilt the micro:bit

What engineering concept allows the pins to be activated?

• Gravity: a force pulls on the pins, activating them when we hold the micro:bit a certain way

• Friction: energy is generated when we rub against the pins, causing them to activate

• Magnetism: the pins are magnetic, so we use a magnet held near them to activate

• Electricity: we touch the pin and Ground, we complete the circuit by conducting electricity through the device

When do we use Conditionals (IF/ELSE) in our code?

• When we want something to happen if some condition is true

• When we want to repeat the same code over and over

• When we want to package multiple lines of code into a single, reusable block.

• When we don't know what the code is going to do next

What is the difference between "IF" and "ELSE IF"?

• "ELSE IF" always starts a conditional statement. "IF" is used when we want to check for other conditions besides the first

• Nothing, either can be used wherever and it won't make a difference.

• "IF" always starts a conditional statement. "ELSE IF" is used when we want to check for other conditions besides the first

• The code inside the "ELSE IF" block only happens if no other condition was true

Which of the following is an example of a condition (something we'd check for in an IF/ELSE conditional statement)

• show string "Hello World"

• temperature > 32

• repeat 4 times

• on start

Which of the following is NOT an example of a condition (something we'd check for in a conditional statement)?

• ammo < 0

• show string "Game Over!"

• activated = True

• tilt > 200

Which sensor on the micro:bit detects the brightness in the surrounding area?

• Warp Drive

• Thermometer

• Logo

• Light Sensor

Which sensor can read the temperature of the room?

• Thermometer

• Light Sensor

• Quantum Core

• Accelerometer

Which of the following is an example of an ANALOG data source?

• A button

• Pin Press

• X-Axis Tilting

• A+B button
