Want to take things up a notch? There are loads of micro:bit accessories available, like sensors, LEDs, and expansion kits. But don’t worry—you can do a lot with just the single board computer itself.

That’s it! No fuss, no steep learning curve. With these basics, you’re ready to start experimenting, learning, and creating. In the next section, we’ll look at how to set up your development board and write your very first program.

What is MakeCode?

One of the best things about Microsoft MakeCode for micro:bit is how easy it is to start programming it, even if you’ve never written a line of code before. The Microsoft MakeCode is the go-to starting point for your programming journey and to explore the applications of micro:bit in real-world scenarios.

MakeCode is a browser-based editor designed to make programming approachable and fun. Its colourful, drag-and-drop blocks will feel familiar if you’ve ever used Scratch or similar tools. You simply snap together blocks to create your program without worrying about typos or complicated syntax.

But MakeCode isn’t just for beginners. As you get more confident, you can switch to JavaScript or even MakeCode Python within the same editor. This means you can see how your block-based code translates into real text-based code, and even start editing it directly. It’s a smooth way to level up your skills without switching platforms.

Here’s how you can do micro:bit programming:

Block Programming:

Drag and drop colourful blocks to build your program. It’s visual, intuitive, and perfect for learning the basics.

JavaScript:

For those ready to dive a bit deeper, you can switch to JavaScript and edit your code directly. This is great for understanding how programming languages work behind the scenes.

MakeCode Python:

MakeCode also offers a Python mode, letting you write code using Python-like syntax. This is a great stepping stone before moving to full MicroPython.

No matter your experience level, MakeCode makes it easy to start simple and grow your skills at your own pace. Whether you prefer snapping blocks or typing micro:bit code, there’s a path for you to bring your ideas to life in programming.

Step-by-Step Setup for Microsoft MakeCode

Getting your micro:bit up and running with Microsoft MakeCode is a straightforward process. Here’s how you can get started, step by step:

1. Connect Your micro:bit to Your Computer

Use a micro-USB cable to connect your micro:bit to your computer. Once plugged in, it will show up as a USB drive called “MICROBIT” on your computer.

2. Open the MakeCode Editor

Launch your web browser and go to the official MakeCode editor at makecode.microbit.org. You don’t need to install anything—everything runs in your browser. If you’re on Windows 10, you can also use the MakeCode app for an even smoother experience.

3. Start a New Project

4. Build Your Program with Blocks

Drag and drop blocks from the toolbox into the coding area. For example, you can use the “show icon” block to display a heart on the micro:bit’s LED grid, or the “on button pressed” block to make something happen when you press a button on the device. Blocks snap together like puzzle pieces, making it easy to see how your program flows.

5. Test Your Code in the Simulator

Before sending your code to the micro:bit, try it out in the built-in simulator on the MakeCode website. This lets you see how your program will work without needing to upload it each time.

6. Download and Transfer to micro:bit

When you’re happy with your program, click the purple “Download” button. This will save a file (ending in. hex) to your computer. Drag and drop this file onto the MICROBIT drive, just like you would with a USB flash drive. The micro:bit coding board will automatically restart and run your new program.

7. Go Portable (Optional)

If you want to use your micro:bit away from your computer, unplug the USB cable and connect a battery pack (with two AAA batteries). Your program will keep running wherever you take it.

With these steps, you’ll have your running custom code in no time. 

How to Power and Connect the Micro:bit via USB

Powering and connecting your micro:bit is a breeze, especially if you’re using a USB cable. Here’s how you can do it:

Step 1: The simplest way to power your development Board is by connecting it directly to your computer with a micro-USB cable. Plug the small end of the cable into the USB port, and the other end into a USB port on your computer. As soon as you connect, your micro:bit will turn on automatically—no need for batteries.

Step 2: When connected, it will show up on your computer as a removable drive called “MICROBIT.” This means you can easily transfer programs to it, just like copying files to a USB flash drive. On micro:bit v1, you’ll see a yellow LED light up on the back. On micro:bit v2, both a yellow and a red LED will light up, indicating power and data connection.

Step 3: When powered by USB, you don’t need to use the battery pack. The USB connection provides enough power for all basic functions, including running code, lighting up the LEDs, and using the built-in sensors.

Step 4: When you’re finished, simply unplug the USB cable from either the computer or the development board. The device will remember the last program you uploaded, so the next time you power it up, it will start running that program automatically
