OBJECT

COUNTER

 

 

 

INTRODUCTION:

In this project we will count the no object. We will display No. of counting on LCD display. We will use 16*2 LCD. we will use Micro switches or reed switches to get data input.

 

MICROCONTROLLER.

In this project we use micro controller to control the direction of motor with proximity switches and monitor the  space of the  parking. Here in this project we use ic 89c2051 controller to sense all the logic. 89c2051 is a 20 pin member of the main 40 pin controller. We use 89c2051 because here in this project we use only 2 output for motor and control signal is only four. Out of four sensor, two sensor  is for the floor  and two sensor for the space. 89c2051 is a small micro controller with 128 byte of ram and 2 k byte of flash memory.

 

How to program a microcontroller.

For programming purpose we wrote a program in the assembly language and  we use any 8051 assembler to assemble the software .
