micro:bit Project: micro:bit Selfie Remote

What is micro:bit?

The Micro Bit is an ARM-based embedded system designed by the BBC for use in computer education in the UK.

The board is 4 cm × 5 cm and has an ARM Cortex-M0 processor, accelerometer and magnetometer sensors, Bluetooth and USB connectivity, a display consisting of 25 LEDs, two programmable buttons, and can be powered by either USB or an external battery pack.

The device inputs and outputs are through five ring connectors that are part of the 23-pin edge connector.

Use the micro:bit as a wireless Bluetooth remote for a smartphone's camera.
