# Arduino

A collection of Arduino / ESP microcontroller projects.

## Projects

- **[WeatherPredictor](WeatherPredictor/)** — autonomous barometric weather
  station on a Wemos D1 mini (ESP8266): local Zambretti forecast, TFT display
  and a self-hosted web interface. See its [README](WeatherPredictor/README.md).

- **[pump_controller_8_2_OLED_DONE](pump_controller_8_2_OLED_DONE/)** — pump
  station monitor on a Wemos D1 mini (ESP8266): watches two main pumps plus a
  backup one, drives two alarm relays, shows status on an OLED and in a web
  panel, and posts events to an HTTPS webhook. Settings live in LittleFS.
  See its [README](pump_controller_8_2_OLED_DONE/README.md) and
  [MANUAL](pump_controller_8_2_OLED_DONE/MANUAL.md).

- **[CPU_temp](CPU_temp/)** — desktop CPU temperature monitor on an ESP32-C3 with
  a built-in 0.42-inch OLED: a Windows agent reads the sensors and feeds the
  board over USB serial, which shows the temperature, CPU load and a one-minute
  history graph, and blinks an overheat alarm. See its
  [README](CPU_temp/README.md).
