Getting Started with Micro:bits

Welcome to the exciting world of micro:Bit! This start-up guide is designed to help beginners get started with the micro:Bit, a powerful and versatile microcontroller that enables you to create a wide range of projects and explore the world of coding and electronics. Let's dive in!

1. Introduction to Micro:Bit

The micro:Bit is a pocket-sized programmable computer developed to introduce beginners to coding and electronics. It features an array of LED lights, sensors, buttons, and other inputs/outputs, making it an excellent tool for creating interactive projects. Before we begin, ensure you have the following:

  • A micro:Bit board
  • A USB cable (usually micro USB) for programming and power
  • A computer with internet access

2. Setting Up the Micro:Bit

  1. Connect via USB: Use the USB cable to connect the micro:Bit to your computer.
  2. Firmware Update (Optional): If your micro:Bit has outdated firmware, you can update it for the best experience. Visit the micro:Bit website ( for instructions on updating the firmware.
  3. Access the Online Editor: Go to the micro:Bit website and click on "Let's Code" or visit directly. This online editor allows you to write code for your micro:Bit.
  4. Select Your Language: In the online editor, choose your preferred programming language. Block-based coding (Scratch-like blocks) is recommended for beginners.

3. Explore the micro:Bit Simulator

Before you start coding on the physical micro:Bit, you can use the online editor's simulator to test your code virtually. It helps you understand how your code will behave before uploading it to the device.

  1. Drag and Drop Blocks: Explore the various code blocks available. Drag and drop them to the workspace to create your code. 
  2. Build Simple Projects: Begin with basic projects like displaying messages, creating animations, and using input buttons.
  3. Interact with the Simulator: Click on the "Download" button to transfer your code to the simulator. Observe how the micro:Bit behaves based on your code.

    4. Writing Your First micro:Bit Code

    Let's create a simple project to get started.

    Project: Displaying a Message

    1. Drag an "on start" block from the "Basic" category to the workspace.
    2. Drag a "show string" block from the "Basic" category and place it inside the "on start" block.
    3. Enter a message (e.g., "Hello, micro:Bit!") inside the "show string" block.
    4. Click the "Download" button to transfer your code to the micro:Bit. It will automatically appear as a removable drive on your computer.
    5. Find the file named "microbit.hex" and drag it into the micro:Bit drive to upload the code.
    6. Watch your micro:Bit display the message you entered!

      5. Exploring Sensors and Inputs

      The micro:Bit has several built-in sensors and inputs that allow you to create interactive projects.

      1. Buttons: Explore the "Input" category to find blocks for the buttons (A and B) on the micro:Bit. Use them to trigger actions in your projects.
      2. Accelerometer: The "Input" category also provides blocks to detect tilting and motion using the accelerometer sensor.
      3. LED Display: Experiment with the "LED" category to control the LED lights on the micro:Bit.

        6. More Resources

        To deepen your understanding and explore advanced projects, consider these resources:

        1. Tutorials: Visit the micro:Bit website for official tutorials and guides (
        2. Community: Join the micro:Bit community forums to connect with other learners and experts.
        3. Projects: Explore project galleries online for inspiration and ideas.

          7. Troubleshooting

          If your micro:Bit isn't working as expected, try the following steps:

          1. Check Connections: Ensure the USB cable is correctly connected to both the micro:Bit and your computer.
          2. Reset: If your micro:Bit becomes unresponsive, press the reset button on the back.
          3. Check Code: Review your code for errors. Double-check for typos and logic mistakes.

            8. Have Fun!

            Remember, the most important part of learning is to have fun! Experiment, tinker, and create exciting projects with your micro:Bit. Happy coding!
