Where have you ever seen digitalRead(trigPin == HIGH) && digitalRead(echoPin == LOW)) //if the sensor hits the fall in front switch reads either 0 or 1 being used to check hitting a wall with what I suppose is an ultrasonic sensor? What do you think

  digitalWrite (trigPin, LOW);
  delayMicroseconds(2); 
  digitalWrite (trigPin, HIGH);
  delayMicroseconds (10);
  duration = pulseIn(echoPin, HIGH);
  distance = (duration/2)/29.1;

is doing?

Also the else of this if(... && ...) is not what you document (it’s an OR not AND)

Please correct your post above and add code tags around your code:
[code]`` [color=blue]// your code is here[/color] ``[/code].

It should look like this:// your code is here
