The sketch turns an ATtiny85 + WS2812 strip into a temperature‐sensing thermometer with ambient‐light–adjusted brightness

This sketch turns an ATtiny (or Arduino) into:
• a rain‐gauge collector (counting bucket‐tips via a reed switch)
• a temperature sensor (NTC thermistor)
• a heater‐controller (PWM output)
• an I²C-slave interface to report rain and temperature data

This component displays a modern semicircular gauge with a value arc, customizable header, and a tiny line chart beneath the gauge. The chart can show recent data points, and each point can be marked with a vertical dotted line. The gauge is highly customizable, supporting color stops, units, tick styling, and more. It’s ideal for dashboards and compact data displays.

Výrobce bohužel neuvádí žádný vzorec pro výpočet odporu, kterým se nastavuje doba do sepnutí. Mimo tabulky jsem nic jiného nikde
