Here's a basic Arduino code for an ESP32 CAM module to connect to a WiFi network

#include "esp_camera.h"
#include "WiFi.h"

// Replace with your network credentials
const char* ssid = "YourSSID";
const char* password = "YourWiFiPassword";

void setup() {
  Serial.begin(115200);

  // Connect to Wi-Fi network
  WiFi.begin(ssid, password);
  Serial.print("Connecting to Wi-Fi");
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.print(".");
  }
  Serial.println("");
  Serial.println("Wi-Fi connected successfully");

  // Initialize camera module
  camera_config_t config;
  config.ledc_channel = LEDC_CHANNEL_0;
  config.ledc_timer = LEDC_TIMER_0;
  config.pin_d0 = 5;
  config.pin_d1 = 18;
  config.pin_d2 = 19;
  config.pin_d3 = 21;
  config.pin_d4 = 36;
  config.pin_d5 = 39;
  config.pin_d6 = 34;
  config.pin_d7 = 35;
  config.pin_xclk = 0;
  config.pin_pclk = 22;
  config.pin_vsync = 25;
  config.pin_href = 23;
  config.pin_sscb_sda = 26;
  config.pin_sscb_scl = 27;
  config.xclk_freq_hz = 20000000;
  config.pixel_format = PIXFORMAT_JPEG;
  
  // Start the camera
  esp_err_t err = esp_camera_init(&config);
  if (err != ESP_OK) {
    Serial.printf("Camera init failed with error 0x%x", err);
    return;
  }
  Serial.println("Camera init successful");

}

void loop() {
  // Capture a photo
  camera_fb_t * fb = NULL;
  fb = esp_camera_fb_get();
  if (!fb) {
    Serial.println("Camera capture failed");
    return;
  }

  // Send the photo to a remote server
  WiFiClient client;
  if (client.connect("www.example.com", 80)) { // Replace with your server details
    String httpRequest = "POST /upload.php HTTP/1.1\r\n" +
                         "Host: www.example.com\r\n" +
                         "Content-Type: image/jpeg\r\n" +
                         "Content-Length: " + String(fb->len) + "\r\n\r\n";
    client.print(httpRequest);
    client.write(fb->buf, fb->len);
    Serial.println("Photo sent to server");
  } else {
    Serial.println("Failed to connect to server");
  }

  // Free the memory used by the photo buffer
  esp_camera_fb_return(fb);

  // Wait for 5 seconds before taking the next photo
  delay(5000);
}

This code connects the ESP32 CAM module to a WiFi network using the provided network credentials. It then initializes the camera module and captures a photo using the esp_camera_fb_get() function. The photo is sent to a remote server using a POST request with the WiFiClient class. Replace the server details with your own server address and the path to your PHP script for processing the image. The code then waits for 5 seconds before capturing the next photo. Note that you may need to adjust the camera configuration based on your module and adjust the delay time between photo captures based on your needs.
