This code is adapted for the ESP32-CAM board Ai Thinker version
It's neccesary install support for ESP32 board to the arduino IDE. In the board manager we need add next link
https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json
Then we can install "ESP32 by Espressif Systems" board in the board manager.
ESP32 lib version: 2.0.16 (ESP-IDF v4.4.7) by Espressif Systems
This project uses other libraries. It is necessary to install them in the arduino IDE.

Arduino IDE configuration for the MCU are stored in the module_XXX.h file.
When flashing the firmware to a new, empty ESP32-CAM device for the first time, it is necessary to use the 'Erase' function.
This can be found under 'Tools' -> 'Erase all Flash Before Sketch Upload' -> 'Enable'.
After the initial firmware upload to the MCU, it is possible to disable this option.
If you do not disable this option, your camera configuration will continue to be erased from the flash memory
after uploading new firmware from the Arduino IDE.
