Program for line following robot

Write down a code for a line following robot which has 2 DC motors, an L298 motor controller and 2 IR sensors. The previous two tutorials can be referred for any doubts.

Reading data from the sensor:

1. First, you need to define the sensor as an inout device using the pinMode function inside void setup():

   pinMode(IRpin, INPUT);
   

2. digitalRead() is used to know the state of the sensor as

   state = digitalRead(IRpin); //This will give HIGH for white surfaces and LOW for black surfaces
   

3. Use if() statements to control the speed of the motors depending on the state of IR sensor

Note: Tinkercad does not have IR sensors in it. So, you only need to submit the code part for this assignment.
