Abstract

Micro controller plays an important role in industries as well as in our day-to-day life. They are programmable devices which are used to control working principles of technologies or functionalities of different application that has been designed based on each and every single instruction that has been given to the Micro controller using assembly language (MPLAB/simulation and Proteus in our project, to design control unit if Microwave oven using micro controller PIC16F872A), and provides desired functions and proper directions in industries. They are also an indispensable part of our daily lives. An average home in Australia, Asia, Europe, Africa and America using these technology. Microcontroller is considered as a basic device or equipment in software engineering and programming. The aim of this thesis is to introduce students to the modeling and designing instructions of control unit of micro wave oven using micro controller for different operation on different components, based on MPLAB and PROTEUS and to use computer simulation as a tool for conducting procedures and control studies. From reading theory the dynamic behavior and interactions that are often not readily apparent and feasible that is why simulation can be very helpful in gaining insights to the different behaviors. Next to having an actual system to experiment on, simulation is often chosen by engineers to study transient and control performance or to test conceptual designs. MPLAB is used because of the short learning instruction that most students require to start using it, its wide distribution, and its general-purpose nature. This will demonstrate the advantages of using MPLAB for analyzing micro controller instructions power system steady state behavior and its capabilities for simulating transients in power systems and power electronics, including control system dynamic behavior.
