Exploring the Micro:bit

What is the primary purpose of the micro:bit?

• To function as a high-end computer

• The primary purpose of the micro:bit is to teach programming and electronics.

• To serve as a smartphone replacement

• To create video games

Name one built-in sensor found on the micro:bit.

• accelerometer

• light sensor

• Moon sensor

• gyroscope

How does the accelerometer on the micro:bit function?

• The accelerometer detects sound waves to measure orientation.

• The accelerometer functions by measuring acceleration forces along three axes to detect motion and orientation.

• It functions by using GPS signals to determine location.

• The accelerometer measures temperature changes to detect motion.

What can the light sensor (LDR) be used for?

• Sound detection

• Temperature regulation

• Motion sensing

• Automatic lighting control, ambient light detection, and brightness adjustment.

How does the micro:bit measure light?

• The micro:bit measures light using an external camera.

• The micro:bit measures light through temperature sensors.

• The micro:bit measures light using a built-in light sensor.

• The micro:bit measures light by analyzing sound waves.

What does the compass on the micro:bit measure?

• The compass measures altitude above sea level.

• The compass measures direction relative to magnetic north.

• The compass measures temperature changes.

• The compass measures speed of movement.

Why is calibration necessary for the compass?

• Calibration is used to enhance the compass's aesthetic design.

• Calibration helps in measuring temperature changes.

• Calibration is only needed for digital compasses.

• Calibration ensures accurate direction by correcting deviations in compass readings.

Where is Button A located on the micro:bit?

• Top side, middle left

• Front side, top left corner

• Back side, bottom right corner

• Front side, center

What type of projects can you create using the accelerometer?

• Text editing software

• Fitness tracking apps, motion-based games, robotics, navigation apps, augmented reality projects.

• Cooking apps

• Weather forecasting tools

How can the light sensor enhance a project like a night light?

• The light sensor allows the night light to operate automatically based on surrounding light levels.

• The light sensor allows the night light to play music when it gets dark.

• The light sensor changes the color of the night light randomly.

• The light sensor makes the night light brighter during the day.
