In this instructable I will teach you how to make a line following robot without using arduino.I will use very easy steps to explain.This robot will use IR Proximity Sensor to follow the line.You will not need any kind of programming experience to build this robot.Only,some interest could make it...
Parts needed:-
Chassis(including wheels and motors)
You can understand how proximity sensor works:- How Proximity Sensor works?
Attach the L293D on the breadboard as shown in the diagram.Make sure that both of the sets of legs of the IC must be on different sides of the breadboard or else they may get connected.If you are a new to breadboard,check this out How does breadboard work?.
