LFR Project

An Arduino LFR project refers to an Arduino Line Follower Robot. This is a popular robotics project for beginners that uses an Arduino board to control a small robot that follows a line on the ground.

• The robot uses infrared (IR) sensors to detect the line (usually black) on a light-colored surface (usually white).
• The IR sensors emit light and then detect the reflected light. When the sensor is over the line, it receives less reflected light.
• The Arduino reads the sensor values and determines which direction (if any) the robot needs to turn to stay on the line.
• By controlling the two motors of the robot, the Arduino makes it follow the line.  

Components:

• Arduino board (Uno is a common choice)
• IR sensor modules (usually 2 or more)
• Motor driver module (e.g., L298N) to control the robot's motors
• Two DC motors
• Robot chassis
• Battery
• Jumper wires

Others :

• Basic electronics concepts like sensors, actuators, and motor control
• Programming with Arduino IDE
• Line following logic
