The program on the microcontroller refers the RC5 code to generate respective output based on the input data to operate a set of relays through a relay driver IC. The main aim of this system is to use it in existing domestic area for operating the loads through the conventional switches or the TV remote. This system…

Automated Paralysis Patient Healthcare System Project

Sensor
Automated Paralysis Patient Healthcare System Project We come across hospitals and NGO’s serving paralytic patients who have their whole or partial body disabled by the Paralysis attack. These people in most cases are not able to convey their needs as they are neither able to speak properly nor do they convey through sign language due to loss in motor control by their brain. In such a situation we propose a system that helps disabled person in displaying a message over the LCD by just simple motion of any part of his body which has motion abilities. This system also takes care of the situation wherein no one is present to attend the patient and thus sending a message through GSM of what he wants to convey in SMS. Our proposed…

Self Balancing Robot Project

Sensor
Self Balancing Robot Project Robotics has been advancing in the recent years with the development of systems bearing more and more complicated designs and handling complicated tasks. Self Balancing Robot is one such step which promotes that a robot should be able to have locomotion using the balancing capabilities just as the humans also possess. This opens for the robots a plethora of task types which they can perform in the way humans do. The Self Balancing Robot Project consists of an Atmega328 microcontroller controlled system which with the help of its sensors mounted on the robot is able to balance the robot in upright posture. If the robot is given a jerk in forward direction to tilt it in forward direction then it will oppose that force and try…

Fingerprint Based Bank Locker System

Sensor
Fingerprint Based Bank Locker System The fingerprint based bank locker system is an enhancement to the traditional bank locker system that uses keys. Now keys can easily be copied and made by theif’s who know about it. Also the keys must be taken care of and can also be lost due to some negligence. Well fingerprint based bank locker system is here to solve all these issues. The fingerprinted authenticated bank locker system is safe as well as easy to use and maintain. No key handling no need to worry about key getting lost. The system uses fingerprint sensing to read fingerprints and first store registered fingerprints against the bank locker record. Now next time a person scans finger the sensor reads it and compares it with past records. Now…
