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!

It’s also an app that can be downloaded for Android or iOS and that simplifies the programming task enormously. You can also code on other editors such as JavaScript, Microsoft Block or Python. You’ll just need to upload the program on a server and then install it on your micro:bit.
