BBC micro:bit: a fully programmable pocket-sized computer
Half the size of a credit card and simple in design, the BBC micro:bit board is offering school teachers a new way of introducing their pupils to the joys of electronics programming.
It is equipped with an ARM processor, numerous pin and I/O ports, colour LEDs, a set of sensors (magnetometer, accelerometer, temperature sensor, etc.), and various programmable buttons. You can connect the micro:bit to a mobile phone using a micro-USB socket. With its Bluetooth Low Energy antenna, it can interact with other devices or connect you to the internet.
Micro:bit school projects
The micro:bit offers many interactivity possibilities (with buttons and a matrix of 25 programmable LEDs, for instance) so you can create all the objects you can think of: a display panel, a weather station, animations, or even small games!
