What is BBC micro:bit?
The BBC micro:bit is a handheld, programmable micro-computer – also known as a micro-controller. This is a computer that’s been shrunk down to a single chip. A self-contained system with a processor, memory and peripherals. Much less powerful than a laptop or tablet, and generally can do only one thing at a time.
It comes with a built-in 5×5 display of 25 LEDs, Bluetooth and sensors. It can be coded from any web browser in Blocks, JavaScript, Python, Scratch and more; no software required. It provides an engaging programming environment, with the ability to connect to and interact with sensors, displays, and other devices.
