Developing a Remote Access System by Interfacing ESP32 Microcontroller with 4X4 Keypad

Remote access with a microcontroller refers to the capability to control and communicate with a system based on a microcontroller from a remote location. The paper discusses the creation of a reliable remote access and control system using the ESP32 microcontroller and a 4x4 keypad. This system blends ease of use with robust security measures. With the increasing demand for secure access control solutions, this system makes a significant contribution to the realm of IoT-based authentication systems. Future endeavors may encompass scalability testing, integration with other biometric authentication methods, and additional refinements to expand its applicability.
