RFID Door Lock System Using ESP32 | How to Make an RFID Door Lock System

In this video, I’ll show you how to build an ESP32-based RFID Door Lock System with a professional IoT web dashboard. This project records user entry and exit time, automatically calculates total stay duration, and allows manual door lock control through a browser — all in real time. The system uses an RFID reader, ESP32, active-low relay, I2C LCD, and buzzer, making it suitable for offices, labs, classrooms, hostels, and smart access control applications. 📌 Source Code + Circuit Scchematic: https://circuitdiagrams.in/esp32-rfid... 📌 Readymade Full Project (PAN India Delivery) https://circuitdiagrams.in/shop/smart... 🔧 Components Used ◆ ESP32 Development Board [https://amzn.to/4caIwv0] ◆ RC522 RFID Reader [https://amzn.to/4sPDqeB] ◆ 16×2 I2C LCD Display [https://amzn.to/4mdreC4] ◆ Active-Low Relay Module [https://amzn.to/4c8ZREz] ◆ Buzzer (Invalid Card Alert) [https://amzn.to/41Ow8Ml] ◆ RFID Cards / Tags [https://amzn.to/4o8wF6l] ◆ Solenoid Door Lock [https://amzn.to/3MwRXfn] ◆ Veroboard / PCB [https://amzn.to/4tvGgGD] ◆ Wires [https://amzn.to/4qjDYY7] ◆ DC to DC Step Down Power Supply Module [https://amzn.to/4tpmqwo] ◆ 12 Volt Power Supply [https://amzn.to/4scyNdt] 📌 In this video, you’ll learn ◆ How an ESP32 RFID door lock system works ◆ How to register and delete RFID users from a web dashboard ◆ How entry and exit time logging is implemented ◆ How automatic stay-time calculation works ◆ How to control the door lock manually from the dashboard ◆ How real-time updates work using WebSockets ◆ How to upload and use ESP32 web dashboard files 📌 Chapters ◆ 00:00 – Introduction ◆ 00:26 – Components Overview ◆ 01:25 – Circuit & Veroboard Assembly ◆ 03:38 – Source Code Process ◆ 07:15 – Web Dashboard Walkthrough ◆ 08:55 – Final Testing & Demo ◆ 11:03 – Conclusion 👉 If you enjoy IoT, ESP32, and Arduino projects, don’t forget to Like 👍, Share ↗️, and Subscribe 🔔 to Circuit Diagrams for more tutorials! 📱 Connect & Follow ◆ 🌐 Website: https://www.circuitdiagrams.in ◆ 🐙 GitHub: https://github.com/tanmoykundu80 ◆ 📘 Facebook:   / circuitdiagrams.in   ◆ 📸 Instagram:   / circuitdiagrams   ◆ 📌 Pinterest:   / creativescanner8481   ◆ ✉️ Email: [email protected] 📌 Hashtags #ESP32 #RFID #IoTProjects #SmartDoorLock #ESP32Projects #ArduinoProjects #RFIDDoorLock #IoTDashboard #EmbeddedSystems #CircuitDiagrams
