Abstract

This project is developed for the users to display the token number using PC.

This mainly consists of PC, PC interface, microcontroller unit and LCD display board.

The design and port programs are written in Visual basic. In the software interface, the user can enter the token number to be displayed in the LCD display. When the user presses the run button, the PC sends corresponding signal to the microcontroller unit through serial port.

The microcontroller receives the signal through RS232 and sends corresponding signal to the LCD driver section.

The LCD controlling section sends signal to the LCD to display the number. Also the PC sends corresponding signal to the audio system to tell the number.

Thus the customer can easily see the token number as well as they can hear the voice.

This system will be very useful in banks to display the token number
