The LM324 Quad Op-Amp Line Follower Robot with Pulse Width Modulation

Designing a simple and yet functional Line Follower Robot (LFR) is always a fascinating and challenging subject to be learned, the LFR actually could be implemented in many ways start from a simple two transistors to a sophisticated PID (Proportional, Integrate and Differential) which take advantage of the programmable feature of microcontroller to calculate the PID equation to successfully navigate the black track line on a white background surface.

hi i just want to ask that for ome reson the motors dont work when i connect them and i check the wiring many times.

@thepspdaxter, recheck your circuit.

Hi,i'm back. What are the value of LDR?

[ermicroinfo]

@meshgheru, you could get a complete information on the website shown on the video

@ermicroinfo thanks but it turned out i connected the VR wrong. it works really great now

@zaiban03329777747, yes you could try it.

@ermicroinfo can i use 100k resistor instead of potentiometer because VR are not available in the market.........?
