Phototransistors T1 and T2 are used for detecting the white path on the black background. The job of the comparator circuit is to convert analog voltage output of the sensor into a digital format for the microcontroller to read.

Computer engineering is a discipline that integrates several fields of electrical engineering and computer science required to R12 and R13 are pull-up resistors. This variation in resistance of the LDRs is used to assess the orientation of the line follower robot in the X-Y plane. The signal voltage at the inverting input uusing the operational amplifier is compared with the fixed reference voltage, which is formed by a potential divider circuit of 5.

Circuit diagram of the comparator section is linw in the figure below. The first part of the program initializes Port follwoing as input port and Port 0 as output part. The abov given program of line follower robot is perfectly rut or not???


When sensor T2 is above the white line, the light gets reflected from the white surface to fall on phototransistor T2. Actually you does not need a microcontroller for implementing such a simple robot.

Your email address will not be published. Holding RST pin high for two machine cycles while the oscillator is running resets the device.

Line Follower Robot using Microcontroller: Project with Circuit Diagram & Code

Concept of line follower is related to light. If this voltage is greater than the reference voltage the comparator outputs a low voltage, and if it is smaller the comparator generates a high voltage that acts as input for the decision-making device microcontroller. Such ISP programmers are readily available in electronic shops and online electronic stores.

You may try the Arduino usiny circuit as well to see how the same project is developed using different controllers. Please enter your comment! Similarly, comparator A2 compares the input voltage from phototransistor T1 with a fixed reference voltage. Door Sensor 19 December 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.

Embedded Hardware Engineer 28 December This condition is maintained until the robot is back on track.

Automated Line Follower Robot

The current supplied by the microcontroller to drive the motor is small. Line follower actually senses the line and run over it. Lastly if there is no deviation to left or right, both motors are kept ON. Very simple and nice project.

autommated Then comparator compares both voltages and generates a digital signal at output. A resource for professional design engineers. Basically two types of line follower robots are: And then in main function we checks inputs and sends output according to inputs to output pin for driving motor. Reply fast sir ….


Few components are unrecognizable. These capacitors are very essential and without them you can expect sudden crashes from the microcontroller side. You can buy this project from our store now Buy Now. The logic executed by the microcontroller for keeping the robot in track is illustrated in the table below. When no light falls on the phototransistor, it is cut-off.

The path to be taken is indicated by a white line on a black surface. Please provide the complete component list.

Embedded-Electronics: line follower robot using

We have used the behaviour of light at black and white surface. IR transmits infrared lights.

Design Guides Product Development: We have used two sensor namely left liine and automsted sensor. 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. Basically, a line follower robot is a self-operating robot that detects and follows a line drawn on the floor.

All Time Fav Videos! The program is written assembly language. Robt microcontroller, based on the inputs from sensor T1 say, left and sensor T2 say, rightcontrols the motor to make the robot turn left, turn right or move forward. The assembly program was converted into hexcode using a free software called MIDE just google for it. Potential Risks of Artificial Intelligence 18 December Can I use gear dc motor with another rpm:
