The micro:bit is an open source hardware ( ARM -based embedded system) designed by the BBC for use in computer education of software developing and hardware learning for kids and adults of all ages. The concept was so perfect that it quickly outgrew UK and to date over two million BBC micro:bits distributed globally in over 50 countries. Not to mention that within previous year it was proud addition to my and Viktor's shelf of educational toys and of course cause and effect for several of our YouTube contributions and several more in production. In the latest video we used micro:bit powered by Elecfreaks' IoT kit with IoT:bit wifi board and assembled a weather station to measure temperature, pressure, humidity and pollution with BME280 and dust particles sensors. Micro:bit was successfully acquiring the weather data every 60 seconds and sent all of them from our test to ThingSpeak website for analysis and chart presentation.
