Summary
In this chapter, we explored the capabilities of the ESP32 microcontroller when it comes to connecting cameras and displays. We began by understanding the ESP32 camera module and its features. We learned how to program the ESP32 camera to capture images and integrate a motion sensor for triggering image capture based on motion detection.
Moving on to display interfaces, we discussed various types of display interfaces, such as SPI, I2C, and parallel. We examined popular display modules compatible with ESP32 and the options they offer for visual output. With this knowledge, we learned how to interface displays with ESP32, configure display pins and connections, and initialize the display module. We also delved into advanced display features such as touchscreen integration.
In the next chapter, we will take our first step toward IoT development with ESP32 by learning about network-based protocols.
