We have already posted few interesting electronics game project. Now, here is one very interesting game projects “Electronics Number Scoring Game” which can give you hour of fun. You can play electronics number scoring game alone or with some friends.
Circuit Description of Electronics Number Scoring Game
The circuit of electronics number scoring game uses two timer ICs i.e. NE 555 (IC1 and IC3) to generate clock pulse and a decade counter to generate mathematical sign. A BCD counter followed by a seven-segment LED display driver is used to generate numbers.
IC2 is a decade counter having ten outputs but here only four outputs are utilized. It is driven by clock pulse from IC1. When switch SW1 is on the set of LEDs ‘run’ so fast that all LEDs appear to glow at the same time. But when SW1 is off, only one set of LEDs glow showing a particular sign. Similarly, in FND500 display numbers o to 9 appear so rapidly that the display always shows 8 but when SW2 is off it shows a particular number from 0 to 9. The arrangement of LEDs to show the signs +, -, ×, ÷ is very important. It should be done according to figure “arrangement of LEDs”.
Several players can participate in Electronics Number Scoring Game, each having one chance having one chance to operate SW1 SW2 alternately.
Scoring of electronics number scoring game projects:
Suppose you have +5, -2 and ×7 in three consecutive chances. Your score is (+5-2) ×7=21. In this way your score is continuous update with every chance. But suppose you get ÷ 4. In this case the pattern of scoring is entirely left to the player’s choice. They can approximate the score like 21÷4 in their own way.
