How to Make a Line Following Robot with LM358 - simple robot

How to Make a Line Following Robot - with LM358 

hello friend, this is my first robotics project, the line tracer robot make without a microcontroller This robot contains no kind of microcontrollers, instead it uses only an integrated circuit (IC LM358) and some other electronics parts. you can make at home very simple low price & you do not need any type of microcontroller hex. file, Arduino programming no problem, you can make it very easily | first time today I make transistor base robot | this project make you need 1/ LM358 ic 2/ DC gear motor 3/ bc547 4/ VR10 / 5/ resistor 10k -100 ohms - 330 ohms 6/ Infrared Tx and Rx LED Pair 7/ 4v battery |

how to work

this Robot is a control mechanism that is completely automatic work  Infrared Tx and Rx LED Pair sensor is work and Acts as a guide, the sensor goes off when the black spot comes on top again the sensor turns on automatically when it comes on the white spot | use tow pair  Infrared Tx and Rx LED sensor right & left similar sensor are fitted both works the same way here two pairs of  Infrared Tx and Rx LED Pair sensor is operated an LM358 OP MP IC | DC motor driver, No ic is used to control the speed of the motor | Used to control the speed of the motor tow bc547 one 10k variable resistor |
