//  Setup for common cathode. For common anode invert the 1's and 0's in table below***
//  You should use resistors(220 Ohm suggested for 5V boards) for each connection beside ground for uniform brightness


//Pin Setup: Change accordingly
int a=6;
int b=5;
int c=12;
int d=11;
int e=10;
int f=8;
int g=9;
int h=13;

byte segmap[][7]={{1,1,1,1,1,1,0},  //0  ***Invert the 1's and 0's for common anode
                  {0,1,1,0,0,0,0},  //1

// the setup routine runs once when you press reset:

    pinMode(segs[i], OUTPUT);
  }
  pinMode(h,OUTPUT);                  //Lets not forget the dot
}

// the loop routine runs over and over again forever:
void loop() {
  for(int i=0;i<=10;i++){            //Iteratate from 0-9, any number less than 0 or greated than 9 will display "E" for error.
    disp7seg(i);
    delay(1000);                    //1000 millisecond(1 second) pause
  }
  disp7segDot(HIGH);                //Turn on the dot and turn it off after 0.5 seconds
  delay(500);
  disp7segDot(LOW);
}

//Dot control function
void disp7segDot(byte state){
  digitalWrite(h,state);
}

//7 segment driver function
void disp7seg(int num){
  for(int i=0;i<7;i++){                          //Iterate through all the segments
    if(num>=0 && num<10){                        //Check for valid number
      digitalWrite(segs[i],segmap[num][i]);      //Light the segment for corrosponding number
    }
    else{

    }
  }
