ESP32 Camera Module Initialization Failure in Image Recognition System for Tissue Samples

Hey guys , am working on an image recognition system that can analyze images of tissue samples, identify malignancies, and predict possible symptoms and causes. The system will utilize a camera sensor for image capture, an ESP32 for processing, and a machine learning model for image analysis. My aim is to set up the ESP32 with the camera module to capture images, How can i interface the camera module with the microcontroller to capture clear images? Am getting the error Camera initialization failed Here's my code

#include <esp_camera.h>

void setup() {
    // Camera configuration
    camera_config_t config;
    config.ledc_channel = LEDC_CHANNEL_0;
    config.ledc_timer = LEDC_TIMER_0;
    config.pin_d0 = 5;  // Adjust based on your wiring
    // Add other pin configurations
    config.pixel_format = PIXFORMAT_JPEG;
    config.frame_size = FRAMESIZE_QVGA;
    config.jpeg_quality = 10;
    
    // Initialize the camera
    esp_err_t err = esp_camera_init(&config);
    if (err != ESP_OK) {
        Serial.println("Camera initialization failed");
        return;
    }
}

void loop() {
    camera_fb_t *fb = esp_camera_fb_get();
    if (!fb) {
        Serial.println("Camera capture failed");
        return;
    }
    // Process captured image
    esp_camera_fb_return(fb);
}

#include <esp_camera.h>

void setup() {
    // Camera configuration
    camera_config_t config;
    config.ledc_channel = LEDC_CHANNEL_0;
    config.ledc_timer = LEDC_TIMER_0;
    config.pin_d0 = 5;  // Adjust based on your wiring
    // Add other pin configurations
    config.pixel_format = PIXFORMAT_JPEG;
    config.frame_size = FRAMESIZE_QVGA;
    config.jpeg_quality = 10;
    
    // Initialize the camera
    esp_err_t err = esp_camera_init(&config);
    if (err != ESP_OK) {
        Serial.println("Camera initialization failed");
        return;
    }
}

void loop() {
    camera_fb_t *fb = esp_camera_fb_get();
    if (!fb) {
        Serial.println("Camera capture failed");
        return;
    }
    // Process captured image
    esp_camera_fb_return(fb);
}

What can I do?

@Boss lady The "Camera initialization failed" error typically means there's a mismatch in your pin configuration or the camera module isn't properly connected. You should verify Pin connections, ensure proper power supply, check camera module compatibility and update ur code with the neccesary pin configurations

#include <esp_camera.h>

#define CAMERA_MODEL_AI_THINKER

#include "camera_pins.h"

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