Project Abstract
<p> This work deals extensively with the design and construction of an electronic dice display (EOD) with audio unit. The device displays the of a ludo dice in numerical form and also produces sound as it displays the number.<br>The device works with principle of chance employee by ludo game players. The output of the display is usually very rapid that the player does actually sex 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 patellar number is displayed and this number is the number, the player got.<br>The operation of the device starts by the generation of a pulse frequency. The pulse frequency (square wave signal) generated by times (555 times) by connecting in an instable multibibrator. The output from this timer is used in clocking the binary counter (mod to counter) but this counter is biased to count just from zero through six (0-6) as we have in a lodo game dice. To achieve this bias in the mod 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 or goes back to zero.<br>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 covert the binary values to the decimal values that are being used in the ludo game dice. The seven segment then displays the numbers by lighting the diodes that make up that particular value.<br>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. <br></p>
