Hello allaboutcircuits forum, anyone knows this circuit? i try to make design but i dont know if its correct, please check my design below






using tinkercad i make this design, do you think its correct? and please tell me where should i put pin 2 and 15 of l293d to lm358/here on the design. The green led is the IR receiver while the gray/white is the IR transmitter, thank you allaboutcircuits forum

How do you intend to follow the line, most line following methods I have seen the that do not use a micro, use only one retro reflective source that is oscillated across the line ?
Or is this a dual line method?

yes, this is dual line method. 2 IR sensor is connected to lm358

 

Is this a circuit that is known to work, as it appears rather simplistic, i.e. fine tuning appears rather minimal?

yes, can you help?

 

The only ones I have any experience with is the older trace cutting tables that pre-dated the CNC Oxy flame cutting tables.
Evidently one similar to the design you show uses an Arduino.
