Virtual Dice Using Arduino

This is a virtual dice. It requires the following items:

10x     Jumper Wires
7x       LEDs
7x       330 Ohm Resistors
1x       10k Ohm Resistor
1x       Button
1x       Breadboard or Perfboard
1x       Arduino Mega 2560 or Arduino Uno

This project takes about 30 minutes to an hour to make.

This is the code that I used:

int pinLeds1 = 10;
int pinLeds2 = 9;
int pinLeds3 = 7;
int pinLed4 = 8;
int buttonPin = 6;
int buttonState;
long ran;
int time = 2000;

void setup ()
{
  pinMode (pinLeds1, OUTPUT);
  pinMode (pinLeds2, OUTPUT);
  pinMode (pinLeds3, OUTPUT);
  pinMode (pinLed4, OUTPUT);
  pinMode (buttonPin, INPUT);
  randomSeed(analogRead(0));
}

void loop()
{
  buttonState = digitalRead(buttonPin);
  if (buttonState == HIGH){
    ran = random(1, 7);
    if (ran == 1){
      digitalWrite (pinLed4, HIGH);
      delay (time);
    }
    if (ran == 2){
      digitalWrite (pinLeds1, HIGH);
      delay (time);
    }
    if (ran == 3){
      digitalWrite (pinLeds3, HIGH);
      digitalWrite (pinLed4, HIGH);
      delay (time);
    }
    if (ran == 4){
      digitalWrite (pinLeds1, HIGH);
      digitalWrite (pinLeds3, HIGH);
      delay (time);
    }
    if (ran == 5){
      digitalWrite (pinLeds1, HIGH);
      digitalWrite (pinLeds3, HIGH);
      digitalWrite (pinLed4, HIGH);
      delay (time);
   }
   if (ran == 6){
      digitalWrite (pinLeds1, HIGH);
      digitalWrite (pinLeds2, HIGH);
      digitalWrite (pinLeds3, HIGH);
      delay (time);
   }
  }
  digitalWrite (pinLeds1, LOW);
  digitalWrite (pinLeds2, LOW);
  digitalWrite (pinLeds3, LOW);
  digitalWrite (pinLed4, LOW);
}
