DESIGN AND CONSTRUCTION OF AN ELECTRIC DICE DISPLAY WITH AUDIO UNIT.
ABSTRACT

This work deals extensively with the design and construction of an electrodice display (EOD) with audio unit. The device displays the value of a ludo dice in numerical form and also produces sound as it displays the number.
The device works with principle of chance employed by ludo game players. The output of the display is usually very rapid that the player does not actually see the number when the device is switched ON so that it will purely be a game of chance. When the off key is pressed, a particular number is displayed and this number is the number the player got.
The operation of the device starts by the generation of a pulse frequency. The pulse frequency (square wave signal) is generated by times (555 timer) by connecting in unstable multi-vibrator. The output from the timer is used in clocking the binary counter (mode 10 counter) but this counter is biased in the mode 10 counter, the output from Qo, Q1 and Q2 were connected to the reset pins so that once the counter finishes the count of six of goes back to zero.
The result from the binary counter is then fed to the decoder / driver before connecting it to seven segment so that the decoder will be able to convert the binary values to the decimal values that are being used in the ludo game dice. The seven segment then displays the numbers by lightening the diodes that make up that particular.
This device is being regulated by a latch (4-edge triggered flip-flop which has two switches, one is used for putting the power supply and the other two push switches for the working of the dice display.

INTRODUCTION
Instrumentation engineering has advanced widely with the introduction of medium scale integration (MIS), large scale Integration (LSI) and very large scale Integration (VLSI). For the purpose of accuracy and reliability analogue instruments are being replaced by the digital ones. The electronic dice display (EDD) with audio unit is among this now bread of instruments.
1.0              STATEMENT OF PROBLEM.
The design of an electronic dice display is invented because of the quest fort reducing strenuous activities encountered by man, especially on the area of its recreational activities. This device is used in ludo game. The ludo game on its manual operation, as he manipulated by the experts so that it can no longer be a game of chance. Sometimes players can employ tricks on their opponents which playing the game, for example if the both players are not vigilant, one of the them can event thwart the dice and claimed that nothing happened. The players too may get tired after playing two or three times because of the stress in shaking and playing the dice, the frequent hitting of the dice on the ludo board can even give cracks on the glass covering the ludo board. One can even  experience the dice getting lost in the game because the dice is very small so if care is not taken, it can fall out from the board. All these problems were taken into consideration before constructing the electronic dice display.
1.1       PURPOSE OF THE STUDY.
As stated earlier, the design of this device is to help man conquer his environment. With the advent of medium scale integration (MSI), Integration circuit (IC) can be used to design devices that can help man perform his work effectively. With little or no stress and even sometimes at a cheaper rate. The device too will eradicate all the stress, tricks and pranks encountered when playing ludo game.
1.2       AIMS AND OBJECTIVES
The device will increase the fun derived from playing the game, even little kids can now join since they only need to press the buttons for the device to work. The game will now be purely based on chance because all bias will be eradicated, no expert can manipulate the device no matter how many times you use it. the normal phenomenon of playing tricks will be a thing of the past.
 1.3              SCOPE OF THE STUDY
The work covered that playing and displaying of number got. This that the device when switched ON and STAR button is pressed, a particular number will be shown and this is the number the player got. This means that the player still need to get a ludo board and the seeds for the game.
1.4              DEFINITION OF TERMS
AND GATE.
It is  a circuit which gives a high outputs (ie logic 1 = high and logic O = low)an AND gate is represented by a dot to indicate it is a multiplication.
COUNTER:
A circuit, which gives output pulse for every two inputs pulses. If the input pulses are irregular the circuit is regarded as counter. Counters usually come as integrated circuit.
Decoder/driver:
 A decoder can be the reverse of an encoder circuit, there are a variety of decoders designed for specific purpose. In this case it is used as a code converter where it is required to convert from binary coded decimal (BCD) to decimal.
Diode:
Diode are two terminal devices which exhibit low resistance to current flow in the other.
FLIP FLOP:
It is a continual logic that can be able to hold one bit at a time.
LATCH:
A latch is a combination of flip flops, in the particular (IC 7474) latch, it has a combination of 4 positive edge triggered flip flops. It changes state on reseipt of an input signal but a way that it does not change state.
MULTIVIBRATOR (ASTABLE)
They are flip flops that has no stable state. It is called astable or free running multivibrator. These type of logic circuit switches back and forth (oscillates) between unstable states. Useful for providing clock signals for asynchronous digital circuits.
RESISTORS:
Resistors provide us with a means of controlling voltage in a circuit electronic circuit.
SWEN SEGMENT DISPLAY:
This is a method of displaying the numerals from 0 – 9 by illuminating 2 or more elements out of the seven arranged in a form. If all the elements 1,2,7,5 and 4 are illuminated a 5 is displayed. Seven segment display is extensively used in electronic equipment e.g recoders, calculators and digital watches.
TIMER:
Timers are used to generate continuous waves or pulse frequency which is usually used for linear applications such as low level amplification, for switching applications, high frequency application and can also be designed to handle high voltage.
