The author of this repository (information, scripts, code) take no responsibility for your use or misuse (or any damage to your devices)! Respect the law in your country/location/area! The information included at this repository is for educational purposes only!
Depending on your
ESP32microcontroller device, sensors and environment you may need to adapt values for GPIO pins. The important values are defined as constants after imports. Many of the examples also run on theESP8266,RP2040/Picoor other MicroPython compatible devices, you have to adjust the pins!
If you do not yet own an ESP32 microcontroller or are unsure about your circuit, on wokwi or Tinkercad you can test mostly all scripts and simulate your circuit/code inside the browser.
