What is Dice ?
A dice is a small object which has multiple landing positions and used for generating random number. Dice is mainly used in gambling and contests.
Recommended Project: Dice using 7 Segment Display
Working of the Project
1. Digital dice is a smarter way to play games such as snake ladder, monopoly etc than the traditional dice.
2. The generation of clock is done by using a 555 timer which is connected in the astable mode at a frequency of approximately 50 Hz.
3. This clock signal is fed into the decade counter outputs of which are connected to 4 bit binary adder which provides a binary output equivalent to binary input + 1.
4. The outputs are then connected to a BCD to 7 Segment Decoder which is used to drive a common anode 7 segment display.
5. As shown in the schematic above, when push button PB is pressed, a square output will be generated from the 555 timer which gives a frequency of approximately 50 Hz to the 7490 decade counter IC.
6. The frequency of the astable 555 timer is calculated by using the standard formula of the timer.
f = 1.44/(1K + 2*1K)(0.01uF) = 48 Hz
