DESIGN AND IMPLEMENTATION OF QUEUING DISPLAY AND SOUND SYSTEM

Presentation on DESIGN AND IMPLEMENTATION OF QUEUING DISPLAY AND SOUND SYSTEM

INTRODUCTION
The queuing display system is a system that displays the servicing number, counter number which is usually used in the bank, payment counter and other service counters.
OBJECTIVES
  1. To design and implementation of 8051-Based Queuing display system.
  2. To design and implementation of corresponding sound system.

QUEUING DISPLAY AND SOUND SYSTEM
Microcontroller
Port 3.0 is connected to pushbutton switch.
Port 3.1-3.5 is connected to seven segment’s common pin
Port pins 1.0 - 1.3 are connected to LED’s.
Pins 1.4 - 1.7 are connected to pushbutton switch.
Pins 2.1 - 2.7 are connected to seven segment displays.

FUTURE PLAN
  1. The sound system can be digitalized by using computer software interfacing with the circuit switch.
  2. Microcontroller can be used for randomly sound selection.
CONCLUSION
  1. Economic operation is important for any equipment.
  2. The components using in this project are available.
