Initialize the ‘Initialize Line Following’ block to set up advanced line following. There are two options: one involves using two infrared (IR) sensors, which operate on analog values or can be connected externally to the left and right infrared sensors with analog pins. The pin configuration must be specified for the “set pin for Line Follower with two IR block.”. The second option is to use three infrared sensors, which function on an external digital pin, and the pin settings must be configured for the “set pin for Line Follower with three IR block.”
