This document describes a colour code security system that uses RGB colour modules to create 16.7 million possible colour combinations for colour cards. The system uses an ATMEGA8 microcontroller, L293D motor driver, IR receiver and emitter sensors, LCD display, programmer board, speaker, and motor. It works by detecting the unique analog values of each colour on a card based on factors like colour smoothness, brightness, and distance from the sensor. The circuit diagram and some improvements are discussed, such as using external RAM to make the system faster.

2.  We take the opportunity to convey our profound and
sincere gratitude to our Prof. Pallab Mandal for
suggesting the project as well as for his constant
guidance, valuable suggestion and inspiration
throughout the project. we would like to thank Dept.
of Computer Sc. College of Engineering &
Management, kolaghat. We would like to also thank
our class mates and all those who played a vital role
either directly or indirectly in the accomplishment of
this Project.

5.  16777216 possible combinations of colour code can be created using RGB
colour module. Similarly using the RGB module many combinations of
colour card can be made for this project and it is secure from other
security systems because in this every colour has an analog value and
that analog value has been used in this development of the security
system. The analog values for every colour depends on the smoothness
of the colour layer, brightness of the colour, external light source,
distance of the colour from the sensor.

6. HOW IT WORKS

7. Hare we use :
>> ATMEGA8(microcontroller)
>> L293D(motor driver)
>> IR receiver & emitter (sensor)
>> LCD(display)
>> Programmer board( arduino)
>> 8 Ω speaker
>> USB cable
>> Motor

8.  This is the circuit diagram of our project:

11.  16777216 no of combination card can be created with RGB
colour…
 Physical layout can be improved …
 This device can be made more faster using external RAM.
 This card is very sensitive so it have to be handle with care…
