The Micro Bit measures 4 × 5 cm the device 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.
This ebook investigates using the Arduino IDE with the board and has many examples.
We look at on board features like the led matrix, accelerometer and magnetometer
We have some basic examples of connecting components to the micro:bit
We then connect various sensors such as temperature, pulse and accelerometers to the board
