electronic device with this digital circuit!
I made a dice throwing prototype: if you press the button, a random number between 1 and 6 is generated and the corresponding number of LEDs are lit up. This was a holiday project with my kids :)Dice throwing prototype using Arduino UNO, a button switch and 6 LEDs.
Now connect the led's negative terminal to the 220ohm resistors and positive terminal to the arduino's digital pins from 2 to 7.and connect the other led of the resistors to the Gnd(ground) pin.
I have added the BRIDGE like structure at the middle of the breadboard for the led's to rest in front of the wires and resistors JUST TO LOOK CLEAN.
We are living in a digital world, so why not to make a digital electronic dice for game. Here We are presenting a compact Electronic Dice with PCB design. You can break the PCB in two if you want to reduce the Dice size.
Dice have 1 to 6 count. So we are using 7 LEDs that displays the patterns same as Dice. It consists of 7490 Counter IC and CD4093 NAND gate IC. Binary counter is configured to count a 3-bit value such that it can diplay Dice numbers in proper way. This counter is resets when it gets 7 count that will not be displayed. To reset the counter IC2A and IC2B two NAND gates are used in such a way that it makes AND gate and another reset comes from QA. When QA, QB, QC all three bits become High Counter gets reseted. To drive 4 LEDs we have used BC548 transistor.
We need the pulses that are generated at very high frequency. When Switch S1 is pressed these puses are fed to counter, we can't predict how many pulses fed to counter so we can't predict the what nuber is going to displayed on the dice. Clock pulses are generated using NAND gate oscillator is formed using R9 and C1. For more details on how to make oscillator using NOT gate?
1.CD4093
2. LEDs
3. IC 7490
4. Tectile Switch
5. 1KOhm, 10KOhm Resistors
6. BC548
7. 100pf Capacitor

1. PCB Layout (1:1 size non mirrored)
You can break the PCB in half to reduce the size
Circuit Uses all digital ICs so no need to program anything just assemble and test it
