DIGITAL DICE
[attachment=19284]
1.INTRODUCTION
1.1Dice
A dice is a small throwable object with multiple resting positions, used for generating random number. This makes dice suitable as gambling devices for games like craps, or for use in non-gambling tabletop games.
A traditional die is an often rounded cube, with each of its six faces showing a different number. The design as a whole is aimed at the die providing a randomly determined integer from one to six, each of those values being equally likely. A variety of similar devices are also described as dice; such specialized dice may have polyhedral or irregular shapes and may have faces marked with symbols instead of numbers. They may be used to produce results other than one through six. Loaded and crooked dice are designed to favor some results over others for purposes of cheating or amusement.
1.2Digital Dice
Digital dice is a device that displays, in random, the numbers from 1 to 9 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.
. IC 555 TIMER
The 555 timer IC is an integrated circuit (chip) used in a variety of timer, pulse generation and oscillator applications. Here, it is used in astable mode to generate clock pulse for the decade counter to count.
6. IC 7447 BCD TO SEVEN SEGMENT DECODER
The 7447 IC is a decoder that is connected to the seven segment display. Its function is to light up the proper segments of the display when binary- coded- decimal numbers are applied to its input leads.
7. 7- SEGMENT DISPLAY
A seven-segment display (SSD), or seven-segment indicator, is a form of electronic display device for displaying decimal numerals that is an alternative to the more complex dot matrix displays. Seven-segment displays are widely used in digital clocks, electronic meters, and other electronic devices for displaying numerical information.
Conclusions
An alternative device is obtained that can be used to replace the traditional dice when you are playing games such as snake ladder, monopoly etc.
It can efficiently work on +5V power supply.
555 can generate pulse when connected in astable mode.
Circuit of digital dice is actually a cascaded connection of all ICs that are used.
Games turn out to be digital rather than manual as used to be earlier.
