Fun games circuit / Aezuwan Aziz and Mohd Hasanul Fathi Abu Samah

Fun games circuit is a simple integrated circuit. This circuit can be used to replace a dice in playing games such as snake ladder Jingo, millionaire and others. It can count a number from zero to nine. While when we turn the switch on, the displays will show a random number such as 1, 2,3,4... So on until 9.
This project consists of several devices such as resistor, capacitor, timer 555, two decade counters, switches and a display driver along with a seven segment display. The operation of circuit game should be started by pressing button 2 and button 3 .These buttons are to count upward and down ward counter. On the other hand, button 1 and 4 operate as a reset and power supply to the display .To start with fresh game, first we press button 1 and then press either button 2 or 3. Next, press button 4 the displays will show a random number .Finally to reset it, press button 1. The main objective of this circuit game is to analyze the operation of timer decoder, synchronous counter and seven-segment display.
