Face Recognition And Image Based Password Authentication For Illiterates https://www.hvstechnologies.in/product/hvs-2192-face-recognition-and-image-based-password-authentication-for-illiterates/ https://www.hvstechnologies.in/product/hvs-2192-face-recognition-and-image-based-password-authentication-for-illiterates/#respond Mon, 17 Aug 2026 11:11:41 +0000 https://www.hvstechnologies.in/?post_type=product&p=29030 The proposed Image-Based Password Authentication System for Illiterates with Touch Screen and Face Recognition is designed to provide a simple, user-friendly, and secure access control system for homes, poultry farms, offices, and industrial applications. Unlike conventional password systems that require remembering letters, numbers, or special characters, this system uses a sequence of images as a password, making it easier for illiterate and elderly users to operate. A touch screen is used to select the predefined images, and the microcontroller verifies the entered image sequence. If the password is correct, the door is automatically opened using a DC motor. If an incorrect password is entered, a buzzer provides an alert and the system can send an SMS notification to a predefined mobile number through the GSM modem.

The system also incorporates face recognition technology to provide an additional level of security. A LAPTOP camera captures the user’s facial image, which is processed and compared with the stored facial database using MATLAB software. The identified facial information is communicated to the microcontroller for authentication and access control. An LCD or graphical display provides visual information regarding the system status, while the buzzer provides audible alerts during unauthorized access attempts. By combining image-based password authentication, touch screen interfacing, face recognition, GSM-based SMS alerts, and automatic door control, the proposed system provides a convenient, accessible, and reliable security solution for users who may find conventional text-based authentication difficult.

TFT Touchscreen Controlled Wired Robot With LCD display. https://www.hvstechnologies.in/product/hvs-4885-tft-touchscreen-controlled-wired-robot-with-lcd-display/ https://www.hvstechnologies.in/product/hvs-4885-tft-touchscreen-controlled-wired-robot-with-lcd-display/#respond Thu, 11 Jun 2026 08:48:25 +0000 https://www.hvstechnologies.in/?post_type=product&p=22794 This project presents a TFT Touchscreen Controlled Wired Robot designed for intuitive and interactive robot control using a graphical touch interface. The system consists of two Arduino Uno microcontrollers, a TFT touchscreen display, an L298 motor driver, and DC motors. The touchscreen serves as the user interface, allowing the operator to control the robot’s movements such as forward, backward, left, right, and stop through touch commands. These commands are transmitted through a wired connection to the main controller, which processes the inputs and drives the motors accordingly.

An LCD/TFT display provides real-time status information and control feedback, enhancing user interaction and monitoring capabilities. The robot is powered by a rechargeable battery, while an LM2596 voltage regulator ensures a stable power supply to the electronic components. The L298 motor driver controls the speed and direction of the DC motors based on the commands received from the controller. This project offers a simple, reliable, and low-cost solution for robotic control and can be used for educational purposes, industrial demonstrations, and robotic research applications.

 

Objectives:

  • To design and develop a TFT touchscreen-controlled wired robot using Arduino Uno.
  • To provide an easy and interactive touch-based control interface.
  • To control the movement of DC motors through touch commands.
  • To display robot status and control information on the TFT LCD screen.
  • To implement reliable motor control using the L298 motor driver.
  • To ensure stable operation using a regulated power supply.
  • To enhance user-friendly robotic control for educational and demonstration purposes.
  • To develop a low-cost and efficient robotic control system.
