This simple electronic dice is an ideal starter project to introduce youngsters and those still young at heart to the dark arts of microcontrollers and circuit building. We take you step by step through the process. For your troubles you will build a useful electronic dice. It will put an end to you scrabbling around under the table to retrieve a dice that’s been carelessly tossed and also an end to cheating… It landed on a six! It really did… yeah right.
This simple circuit simulates the rolling of a dice (or ‘die’ to pedants). When the roll button is pressed the display shows random numbers in the range of one to six, after a while the display settles with one number on the LED display.
