Blynk app based door lock



Today’s home security system is deplorable. This article is about a smart door lock system that we created as a wonderful way to improve the home safety system. We used Wi-Fi devices to operate the door lock in the house using the Arduino IDE programme. The microcontroller is linked to a l293d driver IC, which is used to drive the DC Gearmotor forward (Open) and backward (Close), and the motor controls the door lock. In this way, the blynk android programme controls all data. In that app, we made two buttons to control the house door lock. One is open and another is closed using the blynk app, which we can control from anywhere.
