DIY Line Follower Kit Using Arduino

An Arduino line follower robot using IR (Infrared) sensors is a popular and educational project in the field of robotics. This type of robot is designed to follow a predefined path marked by a contrasting line, typically a black line on a white surface or vice versa. Here’s a short note on the key components and functionalities:

1. Arduino Microcontroller: The central control unit of the robot is an Arduino board, such as Arduino Uno or Arduino Nano. It is programmed to interpret signals from IR sensors and adjust the robot’s movements accordingly.
2. IR Sensors: Infrared sensors are used to detect the contrast between the line and the background. These sensors consist of an infrared transmitter and receiver pair. When the sensor is directly above the line, it receives maximum infrared reflection, indicating that the robot is on the correct path.
3. Motor Drivers: The robot is typically equipped with motor drivers that control the speed and direction of the motors connected to the wheels. The Arduino adjusts the motor speeds based on the input from the IR sensors to keep the robot following the line.
4. Chassis and Wheels: The physical structure of the robot, including the chassis and wheels, determines its mobility and stability. The design ensures that the IR sensors are positioned close to the surface for effective line detection.
5. Calibration: Before operation, the robot may undergo a calibration process where it learns the line-following behavior by adjusting the PID parameters based on the surface conditions and lighting.
