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.

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

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

Hello! Can you send me same photos with front and back of pcb?

[ermicroinfo]

@meshgheru, for more information please visit the website address shown on the video

can i use white light instead of blue

[ermicroinfo]

@zaiban03329777747, yes you can

[zaiban03329777747]

@ermicroinfo thanks again for the simple circuit diagram i have made one of this ... now going toward programed one.... thanks again you have pcb circuit diagram?

[ermicroinfo]

@zaiban03329777747, currently I did not make a pcb circuit diagram for this project, I just leave it like this, so anyone can learn and build this simple LFR project.

[zaiban03329777747]

@ermicroinfo ok thanks for the circuit diagram....

[zaiban03329777747]

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

[ermicroinfo]

@zaiban03329777747, yes you could try it.
