Intelligent Microcontroller-Based Doorbell Communication

Microelectronics, wireless, and network technologies are all advancing quickly along with science and technology. At the same time, people's standards of living are continuously rising, and their expectations for the comfort and safety of their living environments are also rising. The design of intelligent voice message doorbells has grown popular because people in smart residential buildings are in more urgent need of a new kind of wireless doorbell product that can integrate the advantages of dependability, security, convenience, and so on. The Arduino microcontroller, ESP32 camera module, key circuit, voice recording and playback circuit, and power circuit make up the design. Via the recording module, outsiders can record voices and leave messages.
