The BBC micro:bit is a small, pocket-sized, low-cost programmable device that can be used to teach computer education in a playful manner.
It has many features, including:
Buttons: Two programmable buttons, A and B, that can be used for input from the user , and a touch sensor
LED display
Sensors: A compass that can detect magnetic fields and movement in degrees ; tilt sensors in 3 dimensions; temperature sensor; light sensor
Motion sensor: A motion sensor
Sound: The latest micro:bit can sense sound and play it back
Reactive system: A reactive system that reacts to external events, such as shaking the device or pressing the 'A' button
On-chip peripherals: An application processor with a variety of on-chip peripherals
While there are a great many optional accessories available, a great many design projects can be done using only the Microbit, clip wires, and everyday craft materials.
It is programmed using MakeCode( https://makecode.microbit.org/ ), a block-based programming environment similar to Scratch, which includes an on-screen simulator. There is also an optional Python editor.
