I need help in line following robot using automatsd. Project Engineer 22 December There are four conditions in this line follower. You can buy this project from our store now Buy Now. Please enter your name robof. Similarly, comparator A2 compares the input voltage from phototransistor T1 with a fixed reference voltage.

You may also like: R12 and R13 are pull-up resistors. The assembly program was converted into hexcode using a free software called MIDE just google for it. Can u send me the pcb file of line following robot using microcontroller.

Lastly if there is no deviation to left or right, both motors are kept ON. Your email address will not be published. Shall you introduce the programming software for this circuit diagram. This explained behaviour of folowing is used in this line follower robot.


In program first of all we defines input and output pin. Phototransistor T2 goes into saturation and conducts.

And when both sensors comes on white line, robot stop. In the circuit, fkllowing sensors phototransistors are used to detect the white strip on a black background. Programming Explanation In program first of all we defines input and output pin.

DIY Line follower robot using microcontroller with Circuit and Program

LM is used as comparator. Useful Raspberry Pi Projects. And then in main function we checks inputs and sends output according to inputs to output pin for driving motor.

A 12MHz crystal is used for providing the basic clock frequency.

The first part of the program initializes Port 1 as input port and Port 0 as output part. It consists of mainly four parts: We have used two sensor namely left sensor and right sensor.

Out of the seven channels available in the IC,only two are used here. The sensor output is fed to the microcontroller, which takes the decision and gives appropriate command to motor driver LD so as to move the motor accordingly.

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

Log in or register to post Comment. Driver section consists motor driver and two DC motors. Monday, December 31, The program is written assembly language.


Automated Line Follower Robot

We shall try to publish C code later. In this PCB layout we have designed a circuit board for line follower and 2 sticks for placing IR sensors. AT89S52 from Atmel is the microcontroller used follpwing. The path to be taken is indicated by a white line on a black surface. You may try the Arduino based circuit as well to see how the same project is developed using different controllers.

Power-on reset is derived from resistor R5 and capacitor C1. So we added a motor driver circuit to get enough voltage and current for motor. The outputs of the microcontroller are fed to the motor driver. The LDR has an inverse relationship between its resistance and the light falling on it.

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. Quote and Order boards in minutes on https: When a particular input line say pin 1 is made high the corresponding output line pin 16 goes low and vice versa.

Out of the four comparators inside LM, only two are used here. Career advice and jobs related to electronics and IOT.
