TRAFFIC CONTROLLER USING � MICROPROCESSOR 8085

WE ARE MAKE

THIS

• The project involves traffic control circuit using 8085 microprocessor.

​

• Through software traffic of North-East-West-South can be controlled

​

• In project traffic lights are LED’s,connected to 8085 microprocessor with PPI (Programmable Peripheral Interface) 8255 and buffers.

​

• Here a model of traffic controller is prepared that gives general idea about how Red, Green and yellow lights can be controlled

​

• . It also helps to study the interfacing circuits with 8085 microprocessor.

​

• 8085 microprocessor can be mapped as memory mapped and I/O mapped.

​

• This project involves study of I/O mapped interfacing.
• In I/O mapping, I/P or O/P devices are connected through 8255 PPI which has three ports
• . In this project two ports are involved, to port A indicating LEDs are connected and to port B seven segments are connected.

​

• As 8085 microprocessor kit used, programming is done in RAM and program is in assembly language.

OF

PROJECT

ADVANTAGE:

1.8085 SIMPLE PROCESSOR

2.TRAFFIC CONTROL USING WITHOUT MAN

3. IT IS AFFERT LESS.DUE TO INSTRUMENT.

4.IT IS LESS BULKY.

DISADVANTAGES:

​

1.8085 HAS NO EXTERNAL MEMORY.

2.IT IS USE IN 8085.

​

3.PROGRAM GIVEN USING WORK IN REPEAT.

​

4.IT IS USE FOR LIMITED APPLICATION.

​

​

​

APPLICATION:

​

1.TRAFFIC SIGNAL CONTROLLING DIFFERENT PLACES.

​

2.WE ARE DONE MORE THAN ONE APPLICAYION USING MICROPROCESSOR WITH SOFTWARE

.

3. LIKE TEMPERATURE CONTROLLER,BOILER CONTROLLER,LEVEL CONTROLLER.ETC…..
