How to program the ESP32-CAM board ?

There are several ways to program the ESP32-CAM board, but the most common method is to use the Arduino IDE. Here are the steps to follow:

Install the ESP32 board in the Arduino IDE. To do this, open the Arduino IDE, go to File > Preferences, and in the “Additional Boards Manager URLs” field, enter the following URL: https://dl.espressif.com/dl/package_esp32_index.json. Then, go to Tools > Board > Boards Manager, search for “esp32” and install the “ESP32” board package.

Connect the ESP32-CAM board to your computer using a USB cable. Make sure the board is powered on.

In the Arduino IDE, go to Tools > Board and select “ESP32 Wrover Module” as the board.

Select the appropriate port in the Tools > Port menu.

Download and install the ESP32 camera library from the following GitHub repository: https://github.com/espressif/arduino-esp32/tree/master/libraries/ESP32/examples/Camera. To install the library, go to Sketch > Include Library > Manage Libraries, search for “esp32 camera” and install the library.

Load an example sketch from the File > Examples > ESP32 > Camera menu. This will open a sketch that demonstrates how to capture and display an image from the camera module.

Modify the example sketch as needed for your project, and upload it to the ESP32-CAM board by clicking the “Upload” button in the Arduino IDE.
