The aim of this project is to design and build a prototype of an automated parking system which will show the number of parking spaces left inside the parking lot. It will have a pre installed number of maximum cars that can be parked. An infra red sensor will count the entry and exit of each car and open the barricade for the entry and exit. The entry and exit system can how ever be chosen. A display on the monitor outside the parking lot will show how many cars can still be parking inside the

a contrasting background‚ usually a black line on a white surface or a white line on a black surface. Usually the line follower robot works on a closed loop feedback algorithm where the feedback from the line sensor is used by the controller for correcting the path of the robot. The sensors are usually LED/LDR‚ LED/Photodiode or LED/Phototransistor pairs and the controller is an electronic circuit which executes the desired feedback algorithm. Gear motors are used for driving the robotic wheels.

PIEZOELECTRICITY AND APPLICATIONS Piezoelectricity is the ability of some materials such as crystals and certain ceramics‚ to generate an electric potential in response to applied mechanical stress or heat. If the piezo crystals are not short-circuited‚ the applied charge induces a voltage across the material. The word Piezo is derived from the Greek “Piezein”‚ which means to squeeze or press. The piezo material exhibits both “Direct piezo electric effect” as well as ‘Converse piezo electric

shaving technology and its ability to persuade consumers to trade up as new improved versions of existing razors were launched. In 1990‚ the Gillette Sensor represented a breakthrough in shaving systems technology with its twin blade cartridge. This product provided a platform for development of other members of the Sensor family‚ including Sensor for Women and the SensorExcel. It was believed that Sensor’s launch and subsequent success saved the company from takeover bids by Revlon. In 1998‚
