Preface
The purpose of this manual is to design and implement a Microcontroller
based Parking system. In short, the Microcontroller based system will keep track
of the number of cars in the parking area. It will not allow more than 16 cars to
park. It will show the number of slots unoccupied, will automatically raise the
Gate arm to allow cars into the parking lot or leave it. It keeps track of the
amount of time a car is parked, the time at which driver leaves the parking lot,
shows current and exit Time and Date and display them on the a LCD. The
microcontroller will finally calculate the cost of parking, for each car parked in
the Parking area. When the amount is paid and the parking operator depresses a
paid button, the exit arm gate is raised, and one unit is added to the total number
of vacant cars in the Parking lot.
The purpose behind developing a Project like this is an attempt to make
learning Microcontroller programming interesting and enjoyable! Making a
connection with a familiar control system such as a typical Microcontroller
based automated parking system is for showing how and why timers, limit
switches, sensors and relays are used.

How to use this Book
This book is prepared for those who are familiar with the basic instructions
of any typical microcontroller and C language, and want to challenge their
knowledge by writing a more complex industrial program: in this case, preparing
a control program for an AVR microcontroller and Arduino board to control a
car parking system.
In the text, the complete implementation of the project is presented to you.
Read it carefully and your job is to re-write your own version of the same
program. Use your simulator software (such as Proteus) or your own
microcontroller hardware to develop a similar program. When you have done it,
simulate your solution and verify if it works perfectly at the first try. If you did
not succeed at the first try, then compare your solution with the one presented in
this text. When you find out what is wrong in your control program, go ahead
and fix it. Try again and again until you get it done right. When you finally
succeed making it, this means you are on the right track towards mastering your
microcontroller programming knowledge. And that is the purpose of this
manual.
The prototype version of the project is actually designed and implemented in
my lab. The control software is presented to you after it is tested on the
hardware, and I have made sure it is functioning 100% according to the designed
specification.

The schematic diagrams of all hardware circuits used in this project are
provided. If you wish, you can even design and implement your own hardware
system similar to mine or even tailor it to the one with more features that you
wish to have. Or, you can still learn by simulating your own program and
checking out its performance against mine. And if you find yourself stuck up at
any step, you can check out my solution against yours!
