hello guys, ive got problem to make a report on my project, battery level monitor using 8085 microprocessor. help me guys

Abstract

The water level Controller is a reliable circuit, it takes over the task of indicating and Controlling the water level in the overhead water tanks. The level of the water is displayed in the LED Bar graph. The Copper probes are used to sense the water level. The probes are inserted into the water tank which is to be monitored. This water-level Controller-***-alarm circuit is configured around the well-known 8 bit Microprocessor 8085. It continuously monitors the overhead water level and display it and it also switch Off the Motor when the tank fills and it will automatically switch On the Motor when the water level is low. The Microprocessor will also indicate the water level over the LED display. All the input and output functions are done through the Programmable Peripheral Interface IC 8255.

Introduction

The processor is the portion of a computer system that carries out the instructions of a computer program and is the primary element carrying out the computer's function. The form, design and implementation of CPU's have changed but their fundamental operation remains the same. The microprocessor contains all the central processing unit (CPU) functions and is the ‘engine' that goes into motion when you turn your computer on. The microprocessor is designed to perform arithmetic and logic operations that make use of small number holding areas called registers.The diagram of microprocessor is given as under:

Also microprocessor is a multipurpose, programmable, clock-driven, register based electronic device that reads binary instructions from a storage device called memory, accepts binary data as input and processes data according to those instructions and provides as output. A microprocessor incorporates most or all of the functions of a central processing unit (CPU) on a single integrated circuit (IC). The first microprocessors emerged in the early 1970s and were used for electronic calculators, using binary-coded decimal arithmetic on 4-bit words. Other embedded uses of 4- and 8-bit microprocessors, such as terminals, printers, various kinds of automation etc, followed rather quickly. Affordable 8-bit microprocessors with 16-bit addressing also led to the first general purpose microcomputers in the mid-1970s.The most reliable circuit is water level Controller circuit which takes the task of indicating and Controlling the water level in the overhead water tanks. The LED Bar graph is used for displaying the water level.The water level is sensed with the help of copper probes. The probes which have to be monitored are inserted into the water tank.This water-level Controller circuit is configured around the well-known 8 bit Microprocessor 8085. It continuously monitors the overhead water level and display it and also switch ‘off” the motor when the tank fills and it will automatically switch On the Motor when the water level is low.
