How it works

The raspberry takes a picture each hour (I can remotely launch command using voice) and then filters the pic (labels: Graphic design, Pink, Magenta, Line, Purple, Design, Illustration, Graphics, Square, Art). The difference between the two determines the light exposition, increasing or decreasing. The sensor switches blue or red



It communicates through Openweathermap to display on the micro:bit the current forecast (Clouds)



The distant micro:bit counter is set to -1 when it switches to red (the speaker plays a sound) and +2 when it swithes to blue (-2)
