Little Runt Rover Robot Project

Description

This is my robot so far. It is a Runt Rover I bought yesterday at a place in Mass. known as "You Do It Electronics" and I have assembled and soldered him under 2 hours. I even have programmed him a bit. The code is written below. This is a test code I have made to see if he can work and he does. I am hoping to turn this robot into a ledge avoiding and obstacle avoding robot. Wish me good luck!!!

Test Code

void setup() {

  // put your setup code here, to run once:
  pinMode(13, OUTPUT);
  pinMode(12, OUTPUT);
  pinMode(11, OUTPUT);
  pinMode(10, OUTPUT);
  pinMode(9, OUTPUT);
  pinMode(6, OUTPUT);
}

void loop() {
  // put your main code here, to run repeatedly:
  Forward(255);
  delay(1000);
  Stop();
  delay(500);
  Backward(255);
  delay(1000);
  Stop();
  delay(500);
  CCW(255);
  delay(1000);
  Stop();
  delay(500);
  CW(255);
  delay(1000);
  Stop();
  delay(500);
}
void Forward(int Speed)
{
  digitalWrite(9, LOW);
  digitalWrite(10, LOW);
  digitalWrite(13, HIGH);
  digitalWrite(12, HIGH);
  analogWrite(11, Speed);
  analogWrite(6, Speed);
}
void Backward(int Speed)
{
  digitalWrite(11, LOW);
  digitalWrite(6, LOW);
  digitalWrite(13, HIGH);
  digitalWrite(12, HIGH);
  analogWrite(9, Speed);
  analogWrite(10, Speed);
}
void CCW(int Speed)
{
  digitalWrite(9, LOW);
  digitalWrite(11, LOW);
  digitalWrite(13, HIGH);
  digitalWrite(12, HIGH);
  analogWrite(10, Speed);
  analogWrite(6, Speed);
}
void CW(int Speed)
{
  digitalWrite(6, LOW);
