The figure shown below depicts the sensor circuit. Career advice and jobs related to electronics and IOT. The sensor senses the light reflected from the surface and feeds the output to the comparator. Here in this line follower robot when sensor senses white surface then microcontroller gets 0 as input and when senses black line microcontroller gets 1 as input.

In program first of all we defines input and output pin. Your email address will not be published.

Automated Line Follower Robot

Driver section consists motor driver and two DC motors. And then in main function we checks inputs and sends output according to inputs to output pin for driving motor. Useful Raspberry Pi Projects. Please provide the complete component list. When sensor T2 is above the black surface, it remains cut-off as the black surface absorbs virtually all the light falling from LED2 and no light is reflected back.


The output of the sensor circuit is followibg from the points labelled A and B in the circuit diagram. The task of the microcontroller here is to control the left and right motors according to the feedback signals from the left and right comparators so that the robot remains on the correct path the black line.

DIY Line follower robot using microcontroller with Circuit and Program

Shall you introduce the programming software for this circuit diagram. Internship — Image Processing Engineer 27 December The outputs of the microcontroller linr fed to the motor driver. When no light falls on the phototransistor, it is cut-off. The control system used must sense the line and maneuver the robot to stay on course while constantly correcting the wrong moves using feedback mechanism, thus forming a simple yet effective closed-loop system.

Top 20 Computer Engineering Projects.

One for the left channel and one for the right channel. Out of the four comparators inside LM, only two are used here. When a particular input line say pin 1 is made high the corresponding output line pin 16 goes low and vice versa.

In our previous projects, we have made a black line follower robot using arduino but this time we are going to make white line fpllowing using microcontroller. Usually, the line follower robot works on a closed loop feedback algorithm where the feedback from the line sensor is used by the controller for correcting the path of the robot.


These capacitors are very essential and without them you can expect sudden crashes from the microcontroller side. Can u send me the pcb file dobot line following robot using microcontroller.

We shall try to publish C code later. When IR light falls on black surface light is absorbed by the black surface and not rays reflect back, so photo diode did not received any light or rays. The line follower robot presented here is designed to follow a black line on a white background. If there is a deviation to right, the program stops left motor and runs right motor and waits until the robot comes back from the deviation. Output of the left comparator is connected to P1.

LM has inbuilt two low noise Op-amp. Quote and Order boards in minutes on https: The hexcode was burnt into the microcontroller using an in system programmer ISP.
