BBC micro:bit Weather Station
The BBC micro:bit is a small powerhouse loaded with cool functions and supported by a suite of excellent development tools and libraries. Its edge connector allows access to goodies like GPIO ports, analog inputs, an I²C bus and an SPI port. To show how to use it we build a small weather station for it.
