Abstract: Advance system which follows a line until that line exists. Generally, the line is drawn on the work floor. It can be either black or white. The line can also be normal visible colour or invisible magnetic field or electric field. The Arduino uno follows the line by using Infra-Red Ray (IR) sensors. There are five IR sensors which makes it an IR sensor array. These sensors read the line and send that reading to Arduino and then control the Arduino uno movement. Arduino uno follows path drawn on the floor. The line will be mainly black on a white surface. If it occurs any line break on its way, the Arduino uno will go forward. If it finds a cross line, the Arduino uno will stop this cross line is start and stop point of Arduino uno movement. Lines and Arduino uno movements can be changed by using programming code easily. If this Arduino uno senses any obstacle in its path, for example, at run time, any employee or any machine senses it on the predefined path of the Arduino uno, then the Arduino uno will either stop for a few seconds or avoid it, then resume its running on an obstacle-free path.
