This video explains in detail how to record images with the ESP32 and the OV7670 camera (with and without FIFO). An SPI TFT display is supported and a basic web server provides the images in the local network. MQTT is used to announce the IP address of the microcontroller and a simple Node.RED flow provides a convenient UI with the image stream embedded.
