Features : It features a wireless system that can sense the heart sound via an electret mic and show the phonocardiogram to a TFT display. The display is in real time. The sound is amplified and stored in a SD card for later use. A 3.5mm headphone port is open for speaker / headphone connection. The sound can be heard locally or transmitted via cheap 433Mhz RF modules to a distance and received via a same receiver pair.
Components used : Atmega328p, SD card module, TFT display, RF 433
Features : This project features a system based on IoT. The GPS module sends real time location data to the database. The location is continuously compared with selected locations or tolling points (Road, Bridge). When the vehicle crosses a selected point toll is added to its corresponding account and bill is sent as monthly issue to the owner. This eliminates the wait for toll and reduces vehicle congestion. The system also monitors speed of the vehicle. It alerts the user comparing with its speed and the limits set in that location by authority. It'll give a warning to the driver for speeding and if the speeding continues it will send the authority a notification. The project also features a distress button for emergency situations that can notify the nearby hospitals and police stations the location of the vehicle. As the precise location is known help can arrive faster.
Components used : Arduino, GPS module, GSM module for GPRS/EDGE connection for connection to the server and SMS notification.
Features : The computer will take image from a camera. The face will be analyzed using MATLAB. The MATLAB program can store faces for recognition and matching. If the face is matched to any of the face in the database then MATLAB will communicate with the arduino connected to the PC. If the face is not recognized then the program will send another signal to the arduino. The Arduino will see the inputs from the MATLAB program and then send an SMS using the GSM module that is connected to the Arduino. The SMS willl contain which person was detected through the camera and if the person is unknown then the SMS will say that an unknown person is detected.

Features : The conception of entrance control is brought about by the means of a card, an RFID card reader and a control board is amalgamated with the server. This is a proximity card with a unique ID number incorporated in it. The card reader interprets the data and sends it to the control board, which is a microcontroller. This microcontroller tests the legality of the data with the incorporated server, which abides the database. The attached server is uploaded with the details of the worker for that unique ID number. The control board confirms whether the person is permitted to enter the precise door or not. If the worker is genuine, then the person is permitted to enter the door. This can also be used as an attendance counter. A card once scanned will indicate a student is present.
Components used : Arduino as microcontroller, Servo as door openar, RFID card reader, RFID cards.
Features : The robotic car is controlled by making a call on the mobile phone attached with the robot. In the course of the call if any button is pressed a ‘dual-tone multiple-frequency’ (DTMF) tone is heard at the other end of the call. The cell phone mounted on the robot perceives this tone and then the robot processes it using the on board microcontroller. The control buttons were used as the following - 4-left, 5-stop, 6-right, 8-forward, 2-reverse.
Components used : Atmega8, Motor Driver, DTMF decoder, Mobile phone.
Features: This finger print project is created to evade security issues of organizations. In this project the finger print sensor reads the thumb print of the related individual and that copy will be contrasted with the image registered prior, if both the images are matching, then the finger print machine activates precise task such as right to enter a protected area, detection of the member of staff/Students Present etc. The project comprises 2 approaches, the primary one is master approach and the next is user approach. The master approach is employed to record the fresh user and provides the method of permission. The master approach has the capability to generate and erase the users from the system. The user approach is a normal approach employed for the verification of the member of staffs. In user approach of permission, formation and removal of an existing user cannot be done. The key idea of this project is to grant authentic right of entry to various divisions in a company by reading the employee’s finger print.
