Ive been trying so hard to find a schematic that does not have an arduino involved to control a servo with a laser. So far what I have is a laser pointing to a photoresistor that is the trigger for the 555 chip to create a pulse width. The pulse width was a bit too much for the servo so I tried to control it by putting in a low pass filter, but then the signal became too small (voltage wise) so I put the signal through an opamp and it is still not working right.
The breadboard and wires are a bit of a mess and would be hard to post a proper picture of it. If anyone knows where I can find a schematic of a basic idea that would be amazing. I'm trying hard to stay away from arduino because I would like to build everything from scratch so that I can try to really understand circuit design. Thank you for any help.
