Microbit Planetary Lander Quiz

What is the primary purpose of using an ultrasonic distance sensor in the planetary lander project?

• To measure temperature changes

• To calculate speed

• To detect light intensity

• To measure the distance from the surface

Which component is used to program the microbit in this project?

• Microsoft MakeCode

• Raspberry Pi

• Arduino IDE

• Scratch

What is the function of the 'trig' pin on the ultrasonic sensor?

• To ground the sensor

• To send a signal to take a reading

• To power the sensor

• To receive the echo signal

In the programming section, what is the purpose of creating a variable called 'distance'?

• To save the battery level

• To keep track of time

• To hold the distance measurement

• To store the speed of the lander

What should you do if the sensor gives strange readings?

• Change the programming language

• Increase the drop height

• Check the wire connections

• Replace the microbit

Why is it recommended to use USB power during code development?

• To improve sensor accuracy

• To increase processing speed

• To avoid draining the batteries

• To prevent overheating

What is a suggested material for the parachute in the lander design?

• Wooden board

• Glass panel

• Plastic bag

• Metal sheet

What is a key consideration when choosing an ultrasonic sensor for the microbit?

• It must be 5V compatible

• It should have a built-in display

• It should be 3.3V compatible

• It needs to be waterproof

What is a potential issue if the microbit beeps continuously?

• The batteries might be low

• The code is incorrect

• The sensor is too far from the surface

• The microbit is overheating

What is one way to test the lander without dropping it?

• By exposing it to sunlight

• By holding and lowering it towards a surface

• By placing it in water

• By shaking it vigorously
