int pins[] = {
  0,1,2,3,6,7,4,5};
  Serial.begin(9600);
  //set pins as inputs
  for(int i=0; i<=7; i++)
  {
    pinMode(pins[i], INPUT);
  }

Do you want to use pins 0 and 1 as INPUT or as Serial? Both is the wrong answer.

  if(command == '01')

Single quotes are for single characters. Which ONE key did you press to get that ONE character in the quotes?

  if(command == '01')
  {
    do
    { 
      digitalWrite(c,HIGH);
      digitalWrite(d,LOW);
      digitalWrite(f,HIGH);
      digitalWrite(e,LOW);
      delay(500);
      digitalWrite(d,HIGH);
      digitalWrite(c,LOW);
      digitalWrite(e,HIGH);
      digitalWrite(f,LOW);
      delay(500);
    }
    while(command != 's');
  }

If the if test were, somehow, to evaluate to true, enter an infinite loop. Why?
