Introduction

Dice Roller

Used widely

in Games

and Casino.

Main Component of project is Stepper Motor and Visual Basic Interface

This device will roll the dice placed in the holes

and the dice will be display in a

mini elevator.

Objective

To design an electronic working dice roller with the use of stepper motor and using program to control

the device.

Problem Statement

How to apply the stepper motor and

parallel port given in

designing a new life

convenient product?

FINAL PRODUCT

CIRCUIT DESIGN CONCEPT

Electronic Part

ULN 2803 was used to

From the program, the output will be send through the parallel

port from pin 2 until 9.

The output is then sent to IC ULN

2803 of pin 1 to 8.

From the ULN 2803 IC the output will be

invert and send to coil of stepper motor.

VCC which is red jumpered were

connected to pin 9 of IC.

Motor 1 ( Pin 11-15 ) and Motor 2 ( Pin 16-18) were connected to Pin 11-18 of

ULN 2803 IC

Pin 9 of the ULN 2803 IC were

grounded.

Conclusion

This objective of this project is

achieved.

It may have the potentials to be marketed in the game industries mainly casinos.

The knowledge of stepper motor and parallel port were successfully

applied.
