Smart Calling Bell System
The Smart Calling Bell System uses an ESP32 microcontroller and Bylink app to notify home occupants when a visitor presses the bell. A piezo buzzer generates a doorbell sound,Person at the door apears in Bylink interface
This project ensures that even in noisy environments or when headphones are worn, the presence of a visitor isn’t missed. It can also be expanded to send mobile alerts or integrate with a camera.
The system uses digital input from a tactile push button, which triggers both sound output and display update logic.
It is compact and suitable for smart homes, offices, and accessible homes for the elderly or hearing impaired.
Built with Arduino IDE and ESP32 libraries, it’s reliable, power-efficient, and has OTA update support.
Future versions will include photo capture, cloud logging, and voice alert features.
