Microsoft MakeCode for micro:bit

Code first, attach a device later

Choose a sample project or start a new one, then build a small interaction such as showing a message when a button is pressed. The editor supports blocks and text-based JavaScript and Python workflows, with tutorials that connect the beginner-friendly blocks to code. Run the project in the simulator to check its behavior without owning a board; the simulator represents inputs and outputs such as the LED display, buttons, compass, accelerometer, and digital pins.

When a physical micro:bit is available, the documented path is to connect it over USB. The browser compiles the program and lets you save the resulting binary, which can be copied to the mounted micro:bit drive. This makes MakeCode useful for classroom exercises and quick experiments that move from a simulated interaction to a device. The editor needs no installation and the official page says it can work offline after it has loaded.

This listing is for the software editor, not the micro:bit hardware. Current price and account requirements for every feature were not established by the product and documentation pages opened.
