Blynk App Based Smart Door Lock System using ESP32

Nowadays the home security system is very poor. This paper is consists of a smart door lock system in this we developed on a great solution to improve the home safety system. Arduino IDE software in this we used Wi-Fi devices to operate the door lock-in the home. The microcontroller is connected to l293d driver IC that driver IC is used to operate the DC Gearmotor in forward(Open) and backward (Close) and the motor is controlling the door lock. In this method, all data are controlling by the blynk android application in that app we are created two buttons to control the home door lock one is open and another one close form the blynk app we can control form anywhere is function is called as IOT.
