line follower robot fritzing circuit using l298n

The DC motors of the robot are connected to the controller using a motor driver IC. This has many peripheral features like programmable UART, two 8-bit timer/counter, two interrupts, external memory access etc. It is an 8 bit microcontroller with 32 programmable I/O pins. The circuit consists of 8051 microcontroller, IR Sensors (with IR transmitter and IR Receiver), L298N Motor Driver Module, Robot Chassis with 4 wheels and 4 motors, battery holder.Ĩ051 microcontroller is the main component of the project. Development Board for 8051 Microcontroller (preferred).Thus depending on the output of IR sensor microcontroller indicates the motors to change their direction. Whenever, the robot moves out to the white surface, it starts reflecting the IR rays and making the output low. When the vehicle is moving on a black line, IR rays are continuously absorbed by the black surface and there is no reflected ray making output high. IR sensor consists of IR transmitter and IR receiver on a board. Whenever robot moves away from its path it is detected by the IR sensor.ĭo you know about How Remote Controlled Spy Robot Circuit Works?

Similarly, if right sensor moves away from the path, robot moves towards its left. If the left sensor moves away from the line, robot moves towards right. When the two sensors are on the line of path, robot moves forward. The robot direction of motion depends on the two sensors outputs. When robot is placed on the fixed path, it follows the path by detecting the line. The two IR sensors are mounted on the fron of the robot facing with the diodes facing towards Earth. The line follower robot needs mechanical arrangement of the chassis. This circuit mainly consists of 8051 microcontroller, two IR sensors, motors and motor driver IC (embedded in a module).
