Teaching Cyber at K12: Microbits

When I introduce programming and logic, I like to start with block coding and then move to Python. One of the best places to start with (especially middle school and younger) is with Microbits.

In this video I introduce Microbits and how to use them in the classroom.

Video Introducing Microbits

What is a Microbit?

Key Features:

• LED display: A 5×5 grid of LEDs you can program to show text, numbers, or patterns.
• Buttons: Two programmable buttons (A and B) for user input.
• Sensors: Built-in accelerometer (motion), magnetometer (compass), and temperature sensor.
• Connectivity: Bluetooth and USB for communication and power.
• Input/Output pins: Connect external components like sensors, motors, or lights.
• Powered by USB or battery pack.

There are multiple benefits to Microbits:

• Provides both block and Python.
• Provides a physical/visual/auditory result from the coding.
• There are lots of add-ons to make the Microbits much more capable at a higher level of CS class.

Existing free curriculum and guide.

The free curriculum is one of the biggest benefits.

There are several benefits to the Makecode site.

• No login needed (no instructor or student accounts needed).
• There are beginner projects that go step-by-step.
• There is the ability to save/download a program if a student does not finish.

A micro:bit is a small, programmable computer on one chip (also called a microcontroller) designed to make learning coding and electronics fun and accessible, especially for beginners and students.

Why Use Micro:bits in the Classroom?

1. Hands-on Learning
Students get immediate feedback as they program lights, sounds, or movements on the micro:bit. This interactivity makes abstract concepts real and exciting.

2. Cross-Curricular Applications
Micro:bits can be used across subject areas:

• Science: Measure temperature, light, or motion
  
• Math: Create timers or counters
  
• Art: Code LED animations or wearable tech
  
• Music: Build digital instruments or sequencers
  

3. Collaboration and Creativity
Many classroom projects encourage group problem-solving, design thinking, and iterative development—skills that mirror real-world engineering and tech practices.

Best Practices

• Pair-programming – two students work together. Any more than some don’t do anything. You could have one per student – but that can be a lot to manage.
• Show them how to reset and reinstall information.
• Start with the emulator on day one and then introduce the actual Microbit after they create the first program. (Otherwise students play with the Microbit rather than learn the concepts of the programming).
