The micro:bit is a small embedded system designed by the BBC for use in education.
The pins on the microbit allow it to communicate to attached components. The pins can light an LED (or an array of neopixels), detect movement with a PIR sensor or drive an electric motor.
The microbit has sensors onboard and can be attached to external devices. It can also display information on its 5x5 LED display and send data wirelessly.
Putting these together, it is possible to make projects:
5x5 display + shake detection with the accelerometer = Magic 8-Ball
5x5 display + shake detection = step counter
5x5 display + temperature reading = thermometer
PIR sensor + alarm = burglar alarm
The microbit runs a
.hex file containing the script and firmware for the device. Each of editors generate a
.hex file which can then be copied over USB to the microbit.
There’s a thriving and welcoming community behind the microbit. If you’re a developer, or are a user and want to find out more, here a few resources:
