Create a Simple Pattern in a 2*2*2 LED Cube

          We had seen the arduino program to turn on disgonal LEDs of a 2*2*2 LED cube in previous blog. Here we will create a simple pattern in the 2*2*2 LED cube using arduino.


Circuit is given here. Complete that circuit and upload the following program to your arduino board.

int f = 8;  //Connect "f" terminal of LED Cube to 8th pin of arduino
int e = 9;  //Connect "e" terminal of LED Cube to 9th pin of arduino
int d = 10; //Connect "d" terminal of LED Cube to 10th pin of arduino
int c = 11; //Connect "c" terminal of LED Cube to 11th pin of arduino
int b = 12; //Connect "b" terminal of LED Cube to 12th pin of arduino
int a = 13; //Connect "a" terminal of LED Cube to 13th pin of arduino

int i=0, j=0, upper_limit=15, delay_time=100;

// the setup routine runs once when you press reset:
void setup() {                
  // initialize the digital pin as an output.
  pinMode(f, OUTPUT);
  pinMode(e, OUTPUT);
  pinMode(d, OUTPUT);
  pinMode(c, OUTPUT);
  pinMode(b, OUTPUT);
  pinMode(a, OUTPUT);   
}

// the loop routine runs over and over again forever:
void loop() {

  for(j=0;j<delay_time;j++)
  {
  
    for(i=0;i<upper_limit;i++)
    {
      //turn on LED 3
      digitalWrite(f, HIGH);   
      digitalWrite(e, LOW);   
      digitalWrite(d, LOW); 
      digitalWrite(c, HIGH);
      digitalWrite(b, HIGH);  
      digitalWrite(a, HIGH);  

      //turn on LED 4
      digitalWrite(f, HIGH);   
      digitalWrite(e, LOW);   
      digitalWrite(d, HIGH); 
      digitalWrite(c, LOW);
      digitalWrite(b, HIGH);  
      digitalWrite(a, HIGH);
    }

    //Turn off LED 3 and LED 4
    digitalWrite(f, LOW);   
    digitalWrite(e, LOW);  

 
    for(i=0;i<upper_limit;i++)
    {
      //turn on LED 5
      
      digitalWrite(f, LOW);    
      digitalWrite(e, HIGH);  
      digitalWrite(d, HIGH);  
      digitalWrite(c, HIGH);   
      digitalWrite(b, HIGH);  
      digitalWrite(a, LOW);   
  
      //turn on LED 6
  
      digitalWrite(f, LOW);    
      digitalWrite(e, HIGH);  
      digitalWrite(d, HIGH);  
      digitalWrite(c, HIGH);   
      digitalWrite(b, LOW);  
      digitalWrite(a, HIGH);   
    }
 
    //Turn off LED 5 and LED 6
    digitalWrite(f, LOW);  
    digitalWrite(e, LOW);   
  } 
  
  
  
  for(j=0;j<delay_time;j++)
  {
  
    for(i=0;i<upper_limit;i++)
    {
      
      //turn on LED 7
      
      digitalWrite(f, LOW);   
      digitalWrite(e, HIGH);   
      digitalWrite(d, LOW); 
      digitalWrite(c, HIGH);
      digitalWrite(b, HIGH);  
      digitalWrite(a, HIGH);  
    
      //turn on LED 8
    
      digitalWrite(f, LOW);   
      digitalWrite(e, HIGH);   
      digitalWrite(d, HIGH); 
      digitalWrite(c, LOW);
      digitalWrite(b, HIGH);  
      digitalWrite(a, HIGH);
    }

    //turn off LED 7 and LED 8
    digitalWrite(f, LOW);   
    digitalWrite(e, LOW);  


 
    for(i=0;i<upper_limit;i++)
    {
      
      //turn on LED 1
      
      digitalWrite(f, HIGH);    
      digitalWrite(e, LOW);  
      digitalWrite(d, HIGH);  
      digitalWrite(c, HIGH);   
      digitalWrite(b, HIGH);  
      digitalWrite(a, LOW);   
  
      //turn on LED 2
  
      digitalWrite(f, HIGH);    
      digitalWrite(e, LOW);  
      digitalWrite(d, HIGH);  
      digitalWrite(c, HIGH);   
      digitalWrite(b, LOW);  
      digitalWrite(a, HIGH);   
    }
 
    //turn off LED 1 and LED 2
    
    digitalWrite(f, LOW);  
    digitalWrite(e, LOW);   
  } 
  
}

          If uploading is successful, a pattern given at the top of this page will be created in your LED cube. By changing the value of "upper_limit", we can adjust the brightness of LEDs. Similarly, by changing the value of "delay_time", we can adjust the speed of illumination.
