Digital dice

Hey everyone. Are you tired of playing a snake and ladder or ludo with old dice? So hence I bought you the digital version of dice.

Connections:

1) One pin of push button to 2 of arduino and resistor

2) Another pin of push button to 5V of arduino

3) Take 7 leds

4) Positive of them to 3, 4, 5, 6, 7, 8, 9

5) negative of leds to gnd of arduino

CODE:

int x, y, z;

void setup() {

// put your setup code here, to run once:

pinMode(2, INPUT);

pinMode(3, OUTPUT);

pinMode(4, OUTPUT);

pinMode(5, OUTPUT);

pinMode(6, OUTPUT);

pinMode(7, OUTPUT);

pinMode(8, OUTPUT);

pinMode(9, OUTPUT);

}

void loop() {

// put your main code here, to run repeatedly:

x=0;

y=x++;

delay(1);

x=y++;

delay(1);

if (x==6){

delay(1);

int x=1;}+

if(digitalRead(2)==HIGH&&x==1)

{digitalWrite(3, HIGH);

digitalWrite(4, HIGH);

digitalWrite(5, LOW);

digitalWrite(6, LOW);

digitalWrite(7, LOW);

digitalWrite(8, LOW);

digitalWrite(9, LOW);

}

if(digitalRead(2)==HIGH&&x==2)

{digitalWrite(3, LOW);

digitalWrite(4, HIGH);

digitalWrite(5, HIGH);

digitalWrite(6, LOW);

digitalWrite(7, HIGH);

digitalWrite(8, HIGH);

digitalWrite(9, HIGH);

}

if(digitalRead(2)==HIGH&&x==3)

{digitalWrite(3, LOW);

digitalWrite(4, LOW);

digitalWrite(5, HIGH);

digitalWrite(6, HIGH);

digitalWrite(7, HIGH);

digitalWrite(8, HIGH);

digitalWrite(9, HIGH);

}

if(digitalRead(2)==HIGH&&x==4)

{digitalWrite(3, HIGH);

digitalWrite(4, LOW);

digitalWrite(5, LOW);

digitalWrite(6, HIGH);

digitalWrite(7, LOW);

digitalWrite(8, LOW);

digitalWrite(9, HIGH);

}

if(digitalRead(2)==HIGH&&x==4)

{digitalWrite(3, HIGH);

digitalWrite(4, LOW);

digitalWrite(5, LOW);

digitalWrite(6, HIGH);

digitalWrite(7, LOW);

digitalWrite(8, LOW);

digitalWrite(9, HIGH);

}

if(digitalRead(2)==HIGH&&x==5)

{digitalWrite(3, HIGH);

digitalWrite(4, LOW);

digitalWrite(5, HIGH);

digitalWrite(6, HIGH);

digitalWrite(7, LOW);

digitalWrite(8, HIGH);

digitalWrite(9, HIGH);

}

if(digitalRead(2)==HIGH&&x==6)

{digitalWrite(3, HIGH);

digitalWrite(4, HIGH);

digitalWrite(5, HIGH);

digitalWrite(6, HIGH);

digitalWrite(7, LOW);

digitalWrite(8, HIGH);

digitalWrite(9, HIGH);

}

}

Are you interested in making your own arduino project and rely on mysources.

If you rely on my sources then you might have your own ideas thatneither I have not uploaded or nor others. So you might leave the hopes oncompleting that project. But there is no need for youas I will helpyou out personally. Yes you heard it right. I will complete your project. Allyou need is just to press this link.

Precaution: arrange leds in the same way I arranged in schematic diagram

How it works: when you read the project you might be thinking it is impossible and I was one of them as arduino can’t take random options. So one of the options is to make it in a loop where if number 1 is first choice then number 2 is second outcome then it repeats. But it would be easy to predict it. So I made it in a way where after each millisecond the value of the outcome increases and after it reaches 6 in a millisecond it again starts from it look

s like it is random but deep it is not.
