ESP32-CAM time lapse with sending picture to the Cloudinary / Blynk

Time-lapse image capture with ESP32 Camera. Camera makes picture in given interval and sends it to the FTP / CLoudinary server and to the Blynk Image widget.

🚀 12.2022 - UPDATE TO BLYNK 2.0 🚀

Project was updated to the new version of Blynk 2.0

Features:

• Sending image in given time laps to the server
• Capture image interval can be set from Blynk
• Taking picture with or without embedded LED flash (can set in the Blynk)
• Can set time interval in Blynk to decide to take or not a image (based on Blynk real time widget and Blynk time input widget)

To build a project, you need to download all the necessary libraries and create the settings.cpp file in the src folder:

#include "IPAddress.h"

// Project settings
struct Settings
{
    const char *blynkAuth = "XXX";
    const int cameraNumber = 1;

    const char *wifiSSID = "YYY";
    const char *wifiPassword = "ZZZ";
    const char *imageUploadScriptUrl = "http://example.com/upload.php";
    const char *version = "1.0.0";
    const char *firmwareVersionUrl = "http://example.com/version.txt";
    const char *firmwareBinUrl = "http://example.com/firmware.bin";

    IPAddress ip = IPAddress(192, 168, 43, 202);
    IPAddress gateway = IPAddress(192, 168, 43, 1);
    IPAddress subnet = IPAddress(255, 255, 255, 0);

    // alarm based on the other ESP32 device
    const char *alarmEnabled = "http://blynk-cloud.com/auth-token/get/V1";
    const char *isAlarm = "http://blynk-cloud.com/auth-token/get/V2";
};

Sending picture from ESP32-CAM to Cloudinary / Blynk

ESP32-CAM makes picture and send it by HTTP POST request to the server via simple PHP script. I followed this tutorial.

On the server, PHP script:

• inserts date and time to the picture and saves picture to the disk
• sends picture to the Cloudinary API
• sets picture public url from Cloudinary to the Blynk Image Widget
• removes picture from server disk

PHP script is located in the Server scripts folder. It's needed to set up your upload_preset, cloudinary URL, and blynkAuthToken.
