Digital Dice Circuit, You all know board games like ludo are incomplete without dice or we can say that dice are heart of board games. As the title of article it tells you that in this article we will discuss about making of a digital dice. After reading this article you will be able to make your own dice and that will be digital one! So be ready to make a digital dice.
Electronic Components Required for Digital Dice Circuit
- 6 LEDs
- One piezo buzzer
- Two diodes of 1N4001
- Seven resistors( 470K, 2.2M, 100K, 1K, 680 ohm, 470 ohm, 2.2K)
- One IC CD4060B
- Two switch (S1 on/off and S2 push button)
- One capacitor ( 470 pF)
- Power supply of 9 V PP3 battery
Circuit diagram of Digital Dice
Construction of Digital Dice Circuit
In this circuit six LEDs are used. Number of LEDs which glow tells the number which appeared on dice. Connect all the components as shown in circuit diagram. Be careful in doing soldering, if you are doing for the first time take help of someone else.
Working / Function of Digital Dice Circuit
The complete circuit depends on single IC CD4060B. This is a 14 stage binary ripple counter this IC also has a built in oscillator which acts as a clock of ripple counter. There are two switches used in the circuit. We know counter keeps on counting as it is enabled and as soon as it is stopped it gives the value which has been counted till that time. So here initially oscillator don’t work, it works when push button or switch is pushed. Since oscillator is not working so the clock will be zero and all LEDs will glow. As push button is pressed, oscillator gets enabled and counting of counter begins. The counting begins from 000 to 101 and then the pattern is repeated further. After 101 as it counts further so both the diodes become reverse biased and reset pin gets activated and counter starts from 000 once again or we can say that the cycle repeats. Till the time we press switch 2 counting continues and as we stop pressing it, counting stopped and existing state represent the number by LEDs. And micro buzzer will sound as long as counting is done.
Now your digital dice is ready.
