Demo – building a Wi-Fi cam

In this section, we will build a simple program for a Wi-Fi cam over a network. We will use a camera module on the ESP32 board and then we will access the camera connected from a browser.

Figure 8.8 shows our demo scenario; the ESP32 board will run on a simple web server. When a browser accesses the ESP32 board, our program will send a response with a picture of the current environment:

For demo purposes, we will use the OV7670 camera module and the ESP-WROVER-KIT board for implementation.

Hardware wiring

If you have the OV7670 camera module and the ESP-WROVER-KIT board, you can attach the camera module into the board directly. You can see my wiring...
