ESP32 RFID Access Control System with Voice Feedback | Arduino project with code
In this project, I built an RFID-based access system that provides real-time voice feedback. When an RFID card is scanned, the system announces "Access Granted" or "Access Denied" through a speaker using the DFPlayer Mini MP3 module. ESP32 project coded in Arduino IDE.
Key Features:
ESP32 microcontroller for control logic
RFID reader for authentication
DFPlayer Mini MP3 module for audio playback
Custom voice prompts for user feedback
Perfect for DIY home security, office entry systems, or tech learning projects.
