MOTIVATION
The motivation to our project “INDUSTRIAL AUTOMATION USING I2C
PROTOCOL” is designed and implements multiple machines programmer. This project has
three important modules; they are sensor, Microcontroller unit and Driver units of the machines.
In this project fans, Lights and AC of the Home or Industries are programmed to ON/OFF at the
particular time. Such applications are motivated us to do the Project successfully.
1.2 STATEMENT OF PROBLEM
Now a day the automation field gets a wide growth in the world wide. Under this
concept here the project is developed. In this project the Home or Industries, fans, lights and AC
are controlled by using I2C COMMUNICATION. For instance, if want to control one oven
unit, it needs to set the schedule for the system at which time it want to switch ON/OFF. Here
the microcontroller follows the timing of the particular machine and control it. In this place the
controller needs to work in real time to meet the dead line, otherwise the right answer become
wrong answer after the dead line.
1.3 RELATED WORK
To complete our project we studied about PIC 16f877A controller and its features. We
also studied how to interface loads with PIC microcontroller, Relays and Relay Drivers. Also we
visited sites how stuff works.com, www.Microchip.com,
1 INTRODUCTION
The project report describes the design Development and Fabrication of One demo unit
of the project work “INDUSTRIAL AUTOMATION USING I2C PROTOCOL” by using
embedded systems.
Now a day, with the advancement technology, particularly in the field of
Microcontrollers, all the activities in our daily living have become a part of Information
technology and we find microcontrollers in each and every application. Thus, trend is directing
towards Microcontrollers based project works. However, in this project work to program the ON/
OFF timings different machines the microcontroller interacts with I2C COMMUNICATION.
Then the decisions are taken with the help of microcontroller and associated software.
The microcontroller block is playing a major role in this project work. The micro
controller chip used in this project work is PIC 16F877A and this is like heart of the project work.
The PIC 16F877A microcontroller is a 40-pin IC.
The entire project was developed in embedded systems. A system is something that maintains
its existence and functions as a whole through the interaction of its parts. E.g. Body, Mankind,
Access Control, etc A system is a part of the world that a person or group of persons during
some time interval and for some purpose choose to regard as a whole, consisting of interrelated
components, each component characterized by properties that are selected as being relevant to the
purpose.
• Embedded System is a combination of hardware and software used to achieve a single
specific task.
• Embedded systems are computer systems that monitor, respond to, or control an external
environment.
• Environment connected to systems through sensors, actuators and other I/O interfaces.
• Embedded system must meet timing & other constraints imposed on it by environment.
• An embedded system is a microcontroller-based, software driven, reliable, real-time
control system, autonomous, or human or network interactive, operating on diverse
physical variables and in diverse environments and sold into a competitive and cost
conscious market.
MPLAB FEATURES
MPLAB Integrated Development Environment (IDE) is a free, integrated toolset
for the development of embedded applications employing Microchip's PIC® and dsPIC®
microcontrollers.
MPLAB Integrated Development Environment (IDE) is a free, integrated toolset

MPLAB IDE runs as a 32-bit application on MS Windows®, is easy to use and
includes a host of free software components for fast application development and super-charged
debugging.
MPLAB IDE also serves as a single, unified graphical user interface for additional
Microchip and third party software and hardware development tools. Moving between tools is a
snap, and upgrading from the free software simulator to hardware debug and programming tools
is done in a flash because MPLAB IDE has the same user interface for all tools.
MPLAB IDE’s SIM, high speed software simulator for PIC and dsPIC (Digital Signal
Processing PIC Microcontroller) devices with peripheral simulation, complex stimulus injection
and register logging
CONCLUSION
The System operated successfully.
7.3 FUTURE SCOPE OF THE PROJECT
This project can be enhanced in future to home and office automation and also to know
how the equipments or mechinaries in the industry are working
