The BBC micro:bit is a small, pocket-sized computer that was designed by the British Broadcasting Corporation (BBC) in collaboration with several tech companies in 2015. It was created to introduce young people to the world of coding and digital technology, as part of the BBC's Make it Digital initiative.

The micro:bit is equipped with a 32-bit ARM Cortex-M0 processor, along with 256KB of flash memory and 16KB of RAM, making it powerful enough to run a variety of programs and projects. It also features a built-in accelerometer, compass, and Bluetooth connectivity, allowing users to interact with and control the device in different ways.

One of the most unique features of the micro:bit is its LED display, which consists of 25 individually programmable LED lights. This display can be used to create animations, display messages, and provide feedback in various projects. Additionally, the micro:bit has several input and output pins that can be used to connect external components and sensors, expanding the range of projects that can be created with the device.

The micro:bit is programmed using a block-based programming language called MakeCode, which is user-friendly and ideal for beginners. Users can also program the micro:bit using Python or Scratch, giving them the flexibility to choose the programming language that best suits their needs and skill level.

The BBC micro:bit is a versatile and powerful tool for learning about coding and digital technology. It has been used in schools around the world to teach students about programming, electronics, and creative problem-solving. Making it a great cross curricular tool. With its compact size, easy-to-use interface, and wide range of features, the micro:bit is a great tool for educators, hobbyists, and makers alike.
