Understanding basic robot movement

Tasks: Make robot move

1. Connest both DC motors to RobDuino controller according to [@tbl:motors_to_RobDuino]:

MOTOR	RobDuino Output pins
Left DC Motor - con. A	D7
Left DC Motor - con. B	D6
Right DC Motor - con. A	D5
Right DC Motor - con. B	D4

Table: Motors connections to RobDuino Output pins. {#tbl:motors_to_RobDuino}

1. Write simple programming instructions to move the robot forward. Make right sequence of programming instructions (e.g. digitalWrite() and delay(time_in_ms) functions) to achive:
   1. move the robot forward,
   2. do it for 3000 ms and
   3. stop the robot.

Questions:

You probably ended up with something like [@lst:051_First_moves]:

void setup()
{
  pinMode(4, OUTPUT);
  pinMode(5, OUTPUT);
  pinMode(6, OUTPUT);
  pinMode(7, OUTPUT);
  
  digitalWrite(7, HIGH);
  digitalWrite(6, LOW);
  digitalWrite(5, HIGH);
  digitalWrite(4, LOW);
  
  delay(3000);
  
  digitalWrite(7, LOW);
  digitalWrite(6, LOW);
  digitalWrite(5, LOW);
  digitalWrite(4, LOW);
}

void loop()
{

}

1. Is this code “easy readable”?
2. Why is readable code important?
