Slow Down Feature of LED Dice Circuit

The project utilizes a LM555 and CD4017 to produce a realistic readout of dice circuit made of LED as well as slow down feature.

The 7 LEDs are positioned on the board in the same positions as the spots on a dice. They simulate the rolling of a real dice as it rolls across the table when they are activated. The LEDs will start flashing when the Touch Plate wires are touched, in a similar manner to a dice rolling over and over. This will gradually slow down to rest and will display a number exactly like the spots on a dice.

To light various combinations of LEDs, the first six outputs of a decade counter are programmed. The LEDs are arranged at one end of the PC board to form the dot layout of a normal dice. To create the pattern for one, three, and five, one extra LED is placed in the center. The sequence to simulate the rolling of a real dice has been jumbled up instead of sequencing each output to correspond to one, two, three, four, five, and 6. The circuit is powered by 9V battery.
