IoT-Based Door Lock System using ESP32 & Blynk | Password Lock with Alerts
In this IoT home automation project, you’ll learn how to build a Smart Door Lock System
using the ESP32, a 4×4 keypad, servo motor, buzzer, and the Blynk IoT platform.
With this system, users can unlock the door by entering a secret passcode on the keypad. If
the wrong password is entered, the system triggers an alert and instantly notifies the owner
via the Blynk app on their phone — providing real-time security and remote monitoring!
Perfect for smart homes, school projects, or IoT experiments — this project teaches you how
to integrate hardware with cloud-based platforms like Blynk to create powerful connected
systems.
This project demonstrates how to interface a keypad and servo with the ESP32, and how to
set up real-time IoT notifications using the Blynk cloud and app. Great for students, DIYers,
and STEM educators looking to explore smart security systems!
