Introduction to the Micro:bit Series Tutorial

We have officially become the designated agent for Micro:bit in China!

In the coming period, we will introduce the increasingly popular development board: Micro:bit. Let’s take a look at our main character.

What is Micro:bit?

Teacher Lance investigated the “background” of micro:bit, and found that this thing has quite a background, it is a project jointly developed by BBC and many big names (including Microsoft, Samsung, ARM, Nordic Semiconductor, and the Wellcome Trust), and its actual use is somewhat similar to Raspberry Pi and Arduino. Micro:bit is closer to Arduino, but Micro:bit is more like a minimal system compared to commonly used Arduino devices like Uno and micro, requiring higher integration with external devices. It comes with a built-in 5×5 LED matrix, providing users with 25 individually programmable red LEDs for display, along with some buttons for users to interact with games and programs. Other built-in components include an accelerometer, magnetometer, and Bluetooth antenna, so getting started with Micro:bit can be easier without external devices.

What functions does Micro:bit have?

5*5 Programmable LED Matrix

Micro:bit is equipped with a 5*5 LED matrix, which can display numbers, English letters, and simple graphics. Of course, it cannot display our profound Chinese characters.

Programmable Buttons

Micro:bit has two programmable buttons, A and B. We can achieve various control effects through these two buttons.

Bluetooth Module

As we all know, Bluetooth can communicate with mobile phones, allowing mobile phones to easily upload programs to Micro:bit or establish control links.

Accelerometer and Electronic Compass

The accelerometer and electronic compass are two high-precision electronic modules that are usually quite large on other microcontrollers, but our Micro:bit has designed these two modules to be the size of a thumb.

Anyway, Micro:bit has many functions! Many! Many! The gameplay is rich! Rich! Rich!

So where can I buy it?
