Project means a complete scheme which consist of detailed technical report, design, drawing notes, specification,, estimate circuit. The project give full detail of all the work required for the structural and financial aspect. The word project consist seven alphabet and every alphabet has importance itself which is given below :


PLANING ›› planning is words which deal with idea of theme which is necessary to accomplish the project construction in such a progressive manner that the constructed project can give a satisfactory response.

RESOURCE ›› resource means providing necessary guidance by same intellectual person to promote the function of planned idea.

OPERATION ›› operation stated the function which is done over a job is accomplishing its construction in a systematic a manner.

JOINT EFFORT ›› the term joint effort represent the function which is done by different person (worker and labor) to reform the construction of project.

ENGINEERING PROJECT ›› it is the function which is done by engineer who provides some specific progressive method to draw the project construction toward satisfactory response.

COMMUNICATION ›› communication is a media for establishing co-ordination among different person and aspect pertaining to project construction.

TACT OF WORKING ›› ‘tact’ means “right judgments and action” of something which is necessary for a progressive construction of a project.

I. Introduction

This digital dice project is an interesting project that will display in random the number from 1 to 6 on the 7 segment display. This is an alternative device that can be used to replace the traditional dice when you are playing games such as snake ladder, monopoly etc. ur aim to this experiment is to inform us or convince us that this project is much easier than the manual dice.

Components used

Capacitors- A capacitor or condenser is a passive electronic component consisting of a pair of conductors separated by a dielectric (insulator). When a potential difference (voltage) exists across the conductors, an electric field is present in the dielectric. This field stores energy and produces a mechanical force between the conductors. The effect is greatest when there is a narrow separation between large areas of conductor; hence capacitor conductors are often called plates.

An ideal capacitor is characterized by a single constant value, capacitance, which is measured in farads. This is the ratio of the electric charge on each conductor to the potential difference between them. In practice, the dielectric between the plates passes a small amount of leakage current. The conductors and leads introduce an equivalent series resistance and the dielectric has an electric field strength limit resulting in a breakdown voltage.

Capacitors are widely used in electronic circuits to block the flow of direct current while allowing alternating current to pass, to filter out interference, to smooth the output of power supplies, and for many other purposes. They are used in resonant circuits in radio frequency equipment to select particular frequencies from a signal with many frequencies.

Resistors- A resistor is a component of an circuit that resists the flow of electrical current. It has two terminals across which electricity must pass, and it is designed to drop the voltage of the current as it flows from one terminal to the other. Resistors are primarily used to create and maintain known safe currents within electrical components.
