Robot Competitions Tutorial - Wall Maze Solving Robot 7

Let's move on to coding part.

First, I define the motor pins.

//M1
	int enA = 5;
	int in1 = 3;
	int in2 = 4;
	//M2
	int enB = 6;
	int in3 = 7;
	int in4 = 8;

Then define the ultrasonics pins
	int trigLF = 11; //Trig - green Jumper
	int echoLF = 10; //Echo - yellow Jumper
	int trigRF = 18; //Trig - green Jumper
	int echoRF = 19; //Echo - yellow Jumper
	int trigF = 16; //Trig - green Jumper
	int echoF = 17; //Echo - yellow Jumper
	int trigRB = 14; //Trig - green Jumper
	int echoRB = 15; //Echo - yellow Jumper
