What is micro:bit?
The BBC micro:bit is a pocket-sized (52 x 42 mm – 2” x 1.75”) computer, 70 times smaller and 18 times faster
than the original BBC micro computers used in schools. The design is appealing to a young public. It features
25 red LEDs used to flash messages and create games.
micro:bit is compatible with different coding languages starting from Block Editor and mobile apps for the
starters, to Python for more advanced users.
micro:bit has an accelerometer so it can detect motion and knows when you are on the move. The built-in
compass knows which direction you are heading in and it uses a low-energy wireless connection to interact with
other devices and the Internet.
Each element is completely programmable via easy-to-use software on a dedicated website (microbit.org)
accessible from a PC, tablet or mobile.
