• Global Variables: A global variable pictureNumber is declared to keep track of the number of pictures taken
and saved to the SD card.
int pictureNumber = 0;
• Setup Function: In the setup() function, several tasks are accomplished:
– First, the brown-out detector is disabled to prevent the ESP32-CAM from resetting during high current
draws (like when the camera is operating).
WRITE_PERI_REG(RTC_CNTL_BROWN_OUT_REG, 0); //disable brownout detector
– The Serial communication is initialized for debugging.
Serial.begin(115200);
– The camera configuration is set up with camera_config_t, including the GPIO pins, XCLK frequency,
pixel format, frame size, jpeg quality, and framebuffer count.
