UNO DIY Line Follower Kit Compatible with Arduino
This is UNO DIY Line Follower Kit or Line follower robot, as the name implies, It is an automated vehicle that follows a visual line embedded on the surface. This visual line represents the path that the line follower robot will take. It usually uses a black line on a white background, but you can change it to a white line on a black background.
This type of line follower robot using arduino is typically used by beginners and students to gain their first robotic experience.
Giant line follower robots are used in industries to aid in the automated production process. They are also used in military applications, humanitarian aid, delivery services, and so on.
Working:
This line follower robot using arduino is a simple Microcontroller-based car with two infrared sensors.
These sensors determine whether the line colour is reflective or not. In this case, reflection means that the surface reflects the light. The White surface is the reflective surface in this case. (Only the black lines have a non-reflective surface.) This means that black tracks do not reflect any light.
The sensor detects whether or not there is any reflective light coming back. Only the sensor will provide an output (there are two types of output). I’ll get to that later). And if there is no reflection, the IR sensor will not produce any output, or the output will be low. The microcontroller ( Arduino UNO) can control the car based on the High and Low Output results. The microcontroller ( Arduino UNO) instructs the car on where to go, when to turn (left or right), and where to stop.
