In this video, we will guide you through the process of creating an OTP (One-Time Password) based door lock system using Arduino and various components like I2C 16x2 LCD, relay, 4x4 keypad, and GSM SIM800L module. The system will enhance the security of your doors by requiring a unique password each time someone wants to gain access.
