The little board with big possibilities – exploring the BBC micro:bit
We’ve been involved in the BBC micro:bit programme for 18 months and we’re excited that there are now more than 700,000 children in schools across the UK learning to code with their micro:bits. These pocket-sized boards were designed to unleash some serious creativity and we’re already seeing new innovative creations come out of the classrooms. The BBC’s main site is at http://www.microbit.co.uk, and there are some fantastic high-level editors there that are, like the hardware itself, built on top of mbed.
As well as the fantastic response to the programme, we’ve had a lot of interest in how people can progress from those visual editors and use C/C++ on their micro:bit, so we recently took the time to put together a few video tutorials for some easy programs that can help anyone get started using mbed. Check them out below!
micro:bit hello world
Discover the easy way to get started with your micro:bit! This demo runs you through the first steps you need to follow to start programing. Learn how to import and run the “Hello World” program, which scrolls a message on the board LEDs.
The micro:bit accelerometer program reads the physical position of the board then translates the x and y positional values as an LED lit up on the display.
micro:bit heart proximity
By experimenting with two micro:bits for this project, you can use the radio TX /RX libraries that are part of the micro:bit DAL to display a proximity meter in the shape of a heart on the micro:bit LEDs, which empties or fills depending on how close the two boards are to each other.
If you’re interested in a little bit of the history of the micro:bit, you can see the original blog post we wrote a year ago when the project was announced. https://developer.mbed.org/blog/entry/bbc-microbit-mbed-hdk/
