How it works

The raspberry takes a picture — North oriented — each hour (I can remotely launch command using voice and get raspberry statement on smartphone using RaspController) and then filters the pic (labels: Graphic design, Magenta, Illustration, Art, Graphics). 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 (Rain)

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 (-3)

To control what the embed software measures, I use the micro:bit electronic light sensor (0). The difference between the two micro:bit counters is the confidence index (-3)
