555 timer photovore (light seeking robot) is unbalanced?
I got the idea from this video: http://www.youtube.com/watch?v=0p76f7YLwzY
In the video, it mentions that he also used a "trim pot to fine tune his robot" If that is what i need, please explain to me with a picture and words how I would incorporate that in the circuit.
I have also attached a schematic that i used to make the circuit., and some pictures of my breadboard setup. Please tell me if there is anything wrong with the setup, or any thing that I could change.
I'm very desperate to get this working, as I have already spent $45 in this robot. Please help me.
Thanks for reading!
