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
- To design and implementation of 8051-Based Queuing display system.
- To design and implementation of corresponding sound system.
WORKING PRINCIPAL
DISPLAY SYSTEM
SOUND SYSTEM
IMPLEMENTATION (DISPLAY PART)
MicrocontrollerPort 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.
IMPLEMENTATION (SOUND PART)
Counter system
Token system
RESULTSDisplay system:
Sound system:
FUTURE PLAN- The sound system can be digitalized by using computer software interfacing with the circuit switch.
- Microcontroller can be used for randomly sound selection.
- Economic operation is important for any equipment.
- The components using in this project are available.
