ABSTRACT
The Embedded Technology is now in its prime and the wealth of Knowledge available is mind-blowing. Embedded technology plays a major role in integrating the various functions associated with it. This needs to tie up the various sources of the Department in a closed loop system. This proposal greatly reduces the manpower, saves time and operates efficiently without human interference. This project puts forth the first step in achieving the desired target. With the advent in technology, the existing systems are developed to have in built intelligence An automation system is one whose function deals with the automated working and control of electrical and electronic devices widely used today. The heart of the automation system is a programmable chip being able to carry out the respective tasks instructed to it without any human intervention.
PROPOSED SYSTEM
This system uses ultrasonic sensor. By use of the sensors the distance between the object and the vehicle is calculated. Motor speed control is done by using PWM. By proper setting of values to the registers the PWM duty cycle cam be varied and also the duration of the pulses are also varied. In accordance to the distance the speed of the motor is varied.
