Arduino Controlled Electronic Dice

Hi guys! Today I would like to share another fun project with you.An electronic dice.With this you don't need any real boring dice anymore.Unfortunately I don't have pictures of my circuit because I did it a time ago.But I have a video :) First here is a video of my dice.

Well I have to accept I have a bad luck :(

So lets gather the parts

-Arduino Uno

-Breadboard

-7xLed 

-7x470 Ohm Resistor

-1x10k Resistor

-Momentary Button

-Jumper Wires

This will be the layout of your leds and pin numbers.

And here is our diagram.

After preparing the circuit upload this code to your arduino.

Arduino Code

---------------------------

const int ledPins[] = { 2 ,3, 4, 5, 6, 7, 8};

const int ButtonPin = 9;

void setup() {

 pinMode(ledPins[0], OUTPUT);

 pinMode(ledPins[1], OUTPUT);

 pinMode(ledPins[2], OUTPUT);

 pinMode(ledPins[3], OUTPUT);

 pinMode(ledPins[4], OUTPUT);

 pinMode(ledPins[5], OUTPUT);

 pinMode(ledPins[6], OUTPUT);

 pinMode(ButtonPin,INPUT);

}

void loop() {

  if(ReadButton(ButtonPin) == true)

  {

    RollDice();

    }

    delay(1);

}

void ShowDice(int number)

{

  int i;

  for(i = 0; i<7; i++)

  {

    digitalWrite(ledPins[i],LOW);

    }

    switch(number)

    {

      case 1:

       digitalWrite(ledPins[6],HIGH);

       break;

      case 2:

       digitalWrite(ledPins[1],HIGH);         

       digitalWrite(ledPins[4],HIGH);

       break;

      case 3:

       digitalWrite(ledPins[1],HIGH);

       digitalWrite(ledPins[6],HIGH);

       digitalWrite(ledPins[4],HIGH);

       break;

      case 4:

       digitalWrite(ledPins[0],HIGH);

       digitalWrite(ledPins[2],HIGH);

       digitalWrite(ledPins[3],HIGH);

       digitalWrite(ledPins[5],HIGH);

       break; 

      case 5:

       digitalWrite(ledPins[2],HIGH);

       digitalWrite(ledPins[3],HIGH);

       digitalWrite(ledPins[5],HIGH);

       digitalWrite(ledPins[6],HIGH);

       digitalWrite(ledPins[0],HIGH);

       break; 

      case 6: 

       digitalWrite(ledPins[0],HIGH);

       digitalWrite(ledPins[1],HIGH);

       digitalWrite(ledPins[2],HIGH);

       digitalWrite(ledPins[3],HIGH);

       digitalWrite(ledPins[4],HIGH);

       digitalWrite(ledPins[5],HIGH);

       break; 

       }

      }

      void RollDice()

      {

        int dice;

        int i;

        randomSeed(analogRead(0));

        dice = random(1,7);

     for(i=0; i<250; i=i+50)

     {

       ShowDice(1);

       delay(i);

       ShowDice(2);

       delay(i);

       ShowDice(3);

       delay(i);

       ShowDice(4);

       delay(i);

       ShowDice(5);

       delay(i);

       ShowDice(6);

       delay(i);

       }

       ShowDice(dice);

       }

      boolean ReadButton(int ButtonPin)

      {

        int okunan = digitalRead(ButtonPin);

        delay(25);

        if ( okunan == digitalRead(ButtonPin))

        {

          return okunan;

          }

          else

          {

            return false;

            }

            }

Now you can enjoy with your dice.By the way it's a fair dice. You can use it while playing backgammon if you don't trust your friend :D or you guys can play Risk and ruin your friendship like us :(. Please write comments about project and the blog I will be happy to improve my blog and tutorials.
