BBC's micro:bit is an ARM-based embedded system with an accelerometer, magnetometer, Bluetooth, USB, 25 LED lights, and 2 programmable buttons, that is part of a BBC initiative to enhance computer education in the UK. The small board should be given for free to all year 7 students in the country to help them write software and build new computer things. It has a dedicated website to get started and desktop applications to connect to computers.
But now students will also be able to try their code on-the-go and wirelessly from their phones thanks to the new Android app. Developed by Samsung (which has partnered with the BBC as part of its Corporate Citizenship program), the app has four main sections to discover others' code on the micro:bit website, write your own code, connect to your micro:bit, and flash new code to see it execute.
There isn't much else to the app but those students who will start getting their micro:bit will be happy to know that they can try new ideas and work on their projects without being tethered to a computer. Oh, and Samsung has its own micro:bit hub to get students going with code as well.
micro:bit is free, but you will need to have the board at hand to use it. They're supposed to be sent to students of year 7 for free, and maybe be available for purchase later on for everyone else.
