Cook, 2004) . Control systems are ubiquitous. They appear in our homes, in cars, in industry and in systems of communication and transport, just to give a few examples. Control is increasingly becoming mission critical , processes will fail if control doesnt work. Control has been important for design of experimental equipment and instrumentation used in basic sciences and will be even more so in the future. Principles of control also have an impact on such diverse field as economics, biology , and medicine (M. Caliskan, 2006). -Hardware Requirements The hardware components used in this project auto parking system are as follows: - Aurdio Uno., - Infra-Red Sensor, - Servo Motor, - Power Supply, - A USB Cable. The illustration of each component of these hardware requirements can be given as follows: - Aurdio Uno The Aurdio Uno is a microcontroller board based on the ATmega328 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started (R. Lu, X,2007 ). -Infra-Red Sensor An infrared sensor is an electronic device that emits and/or detects infrared radiation in order to sense some aspect of its surroundings. Infrared sensors can measure the heat of an object, as well as detect motion. Many of these types of sensors only measure infrared radiation, rather than emitting it, and thus are known as passive infrared (PIR) sensors. All objects emit some form of thermal radiation, usually in the infrared spectrum. This radiation is invisible to our eyes, but can be detected by an infrared sensor that accepts and interprets it. In a typical infrared sensor like a motion detector, radiation enters the front and reaches the sensor itself at the center of the device. This part may be composed of more than one individual sensor, each of them being made from piezoelectric materials, whether natural or artificial. These are materials that generate an electrical voltage when heated or cooled - Servo Motor Radio Control (RC) hobby servos are small actuators designed for remotely operating model vehicles such as cars, airplanes, and boats. Nowadays, RC servos are become more popular in robotics, creating humanoid robot, biologically inspired robot, robotic arm and etc. This is because of its’ ability to rotate and maintain and certain location, position or angle according to control pulses from a single wire. Inside a typical RC servo contains a small motor and gearbox to do the work, a potentiometer to measure the position of the output gear, and an electronic circuit that controls the motor to make the output gear move to the desired position. The features of Servo Motor is given as: - Control position through Pulse Code Modulation - Pulse width range: ~ 0.5ms – 2.5ms - Come with servo horn and screw accessories. Servos are controlled by sending them a pulse of variable width. The signal wire is used to send this pulse. The parameters for this pulse are that it has a minimum pulse, a maximum pulse, and a repetition rate. Given the rotation constraints of the servo, neutral is defined to be the position where the servo has exactly the same amount of potential rotation in the clockwise direction as it does in the counter clockwise direction. It is important to note that different servos will have different constraints on their rotation (Y. Bi, L. Sun, H. Zhu, 2007). - Circuit Connectivity The connectivity of the circuit designed in this project is shown in Fig. 4, where is that how the aurdino board is connected with the other parts of the whole model care, such as sensors and power supply. - Digital Screen A 6 - 15V DC Power Supply with center positive polarity. Paying attention to that when using a power supply with a barrel connector, we have to ensure that the power supply has center positive polarity (Y. Peng, 2006). - Software Requirements The software requirements of this project A.P.S are given as follows: - Microsoft Professional Project, which can called as MS Projects. - Programming : C++. - Documentation : Microsoft word processor and Microsoft power point. - Other: Any software that allow scanning the picture of employee to computer.
