![]() ![]() Then you will be able to download the relevant library by going to the Boards section in Tools > Board > Boards Manager and ESP32 Search. Https : //dl./dl/package_esp32_index.json, To get started, the library for this module must be installed in the Arduino IDE software. First, the following link must be copied and pasted to File > Preferences. This process is done using a cmd in your Windows machine, but of course there are other versions for the Linux machine that allow us to use Raspberry Pi to be able to run the server part of the project. This project works in such a way that by using the ngrok cloud, after registering and receiving the required code and then running the ESP32-CAM web server on the local network with the help of the ngrok cloud, the data is transferred to the cloud and received on the side We will do it again. We communicate. In this module, there are two levels of 3.3 and 5 volts, which can be useful in different projects. In fact, this module is a USB to TTL converter that uses Rx and Tx with ESP-CAM board and via USB connection to the system used. To program ESP32-cam, because the internal programmer is not included, we use this module. After specifying the port that your web server is listening to, the client program starts connecting by connecting the server, and then anyone can request a unique address from their local server.ĮSP32 is the advanced generation of ESP8266. One of the differences is its built-in Bluetooth. It also has a 2.4 GHz WiFi core and built-in Bluetooth with TSMC 40-nanometer technology. This module has the best performance in energy consumption, that is, it brings the best results for us with the lowest energy consumption. If we want to take a closer look at this board, we must say that this is a chip in which the NodeMCU platform is implemented, which is also called System on a chip microcontrollers. Other features of ESP32-cam module We can mention the OV2640 camera with the ability to record images in JPEG, BMP and grayscale formats. You will also be able to shoot in dark places with the LED flash mounted on this module. One of the useful features of this micro SD input module is the ability to upgrade to 4GB, which also allows the user to store images. Ngrok can circumvent NAT and firewall mapping restrictions by creating a TCP tunnel from a randomly created subdomain at (e.g. Similar performance can be achieved with Reverse SSH Tunneling, but this requires more configuration as well as hosting from your remote server. ![]() This software allows your local web server to be hosted under the domain, meaning that no IP or public domain name is required on the local device. Ngrok is a cross-platform application that enables developers to expose a local development server to the Internet with minimal effort. ![]() In fact, once the project is completed and launched, you will only be able to access it with a single link. Visit CiferTech for more tutorials, and be sure to follow my Instagram page to support me. In this tutorial, we are going to use ESP32-CAM boards and Cloud ngrok to build such a device with the ability to send images to different places without any restrictions. In the category of security products, you will see cameras known as ip cameras, which actually deliver the received images to the user through the cloud from anywhere in the world.
