First Lessons with MakeCode and Micro:bit

What platform is emphasized for programming the Micro:bit in the Week 10 Nightlight project?

• Scratch

• MakeCode

• Python IDLE

• Arduino IDE

A class is starting a Nightlight project using a Micro:bit in Week 10. Which step best shows an appropriate first action for students beginning this lesson?

• Solder external LEDs directly to the battery pack

• Open MakeCode and create a new project for the Nightlight

• Disassemble the Micro:bit to access its processor

• Install a smartphone app to replace the Micro:bit

What does a light sensor do on a Micro:bit?

• Measures sound

• Measures brightness of light

• Measures temperature

• Measures movement

When it gets dark, what should the Micro:bit nightlight logically do?

• Turn the light ON

• Turn the light OFF

• Show a smiley face

• Play a tune

Which statement best describes sensors in this lesson?

• They are outputs that display results on the Micro:bit.

• They are inputs that sense things in the real world, such as movement and light.

• They only measure sound and temperature.

• They are used only to play music.

What does logic help the Micro:bit do in your code?

• Make random choices without conditions

• Make decisions in code based on whether things are true or false

• Only read sensor values without using them

• Draw pictures on the LED grid automatically

Which key term matches this description: runs continuously to keep checking the light level and control the nightlight?

• Forever

• Outputs

• Input

• Tune

The if...then condition uses the light sensor value. What comparison does it check?

• Light level equals 100

• Light level greater than 100

• Light level less than 100

• Light level not equal to 0

Why does the program show LEDs only when the light level is less than 100?

• To display a greeting

• Because it indicates a dark environment needing light

• To test the sensor calibration

• To save the steps variable

You are building the nightlight in a new MakeCode project. Which pairing correctly matches the role to its category?

• Light sensor — Output

• LEDs — Input

• Logic comparison (light level < 100) — Logic

• clear screen — Sensor
