MUMBAI, India, Sept. 7 -- Intellectual Property India has published a patent application (202641064157 A) filed by Srm Institute Of Science And Technology Tiruchirappalli on May 21, 2026, for Digital Door Lock Security System Using Arduino Uno.
Inventors include Immanuel Raj S A; Jagad Guru A; Parthasarathy D; and Dr. K. Vaishnavi.
The application for the patent was published on September 04, 2026, under issue no. 36/2026.
Abstract: The present invention describes design, development, and implementation of a Digital Door Lock Security System using the Arduino UNO microcontroller platform, offering a reliable and affordable solution for modern access control applications. The Arduino UNO acts as the central processing unit that receives the input and compares it with a pre-stored password saved in its memory. Based on this comparison, it either grants or denies access through appropriate output actions. When the entered password matches the stored credential, the system displays “Access Granted” on the LCD, the green LED lights up, and the SG90 servo motor rotates by 90 degrees to unlock the door.
