The microcontroller is programmed to make the robot move forward, turn right or turn left based on the input coming from the comparator.

I need help in line following robot using microcontroller.

Line Follower Robot using AT89C51 | Full Project with Source Code

It consists of mainly four parts: And when both sensors comes on white line, robot stop. You can buy this project from our store now Buy Now. Your email address will not be published. Door Sensor 19 December Quote and Order boards in minutes on https: Collectors of phototransistors T1 and T2 are connected to the inverting inputs of operational amplifiers A2 and A1.


And then in main function we checks inputs and sends output according to inputs to output pin for driving motor.

Similarly, comparator A2 compares the input voltage from phototransistor T1 with a fixed reference voltage. When no light falls on the phototransistor, it is cut-off.

Interfacing Nokia At89c15 to Micro Controller Moisture sensing automatic plant watering system using If there is no deviation to right, the program checks for a deviation to left.

The LDR has an inverse relationship between its resistance and the light falling on it.

DIY Line follower robot using microcontroller with Circuit and Program

It provides sufficient current to drive the motor. 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. LM is a general purpose quad usinf which can be operated from a single supply. How to make a PCB at home.

Automated Line Follower Robot

The hexcode was burnt into the microcontroller using an in system programmer ISP. You may try the Arduino based circuit as well to see how the same project is developed using different controllers.


The line follower robot presented here is designed to follow a black line on a white background. Basically two types of line follower robots are: When the robot is back on line again, dollowing motors are started.

Awesome Timer IC Projects. They are able to follow a line marked on a contrasting background, usually a black line on a white surface or a white line on a black surface.

Gear motors are used for driving the robotic wheels. Remaining sections of the circuit were explained already.

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. Can I use IR proximity sensor instead of making my own?

The abov given program of line follower robot at89c1 perfectly rut or not??? You may also like: Concept of Line Follower Robot Concept of line follower is related to light.

Schematic of the motor driver circuit is shown in the figure below. Output from the left and right sensors node A and B are connected to the non inverting input on the left and right comparators.
