Light Seeking Robot
Now most people I now tell me that they can not find a good light seeking robot circuit, but I have a very easy to build simple circuit using a 556 duel timer.Now this robot works on the same principle as the 555 oscillator circuit I posted in an earlier post the only difference is that I swapped the 50k pot for 20k photo resistors. You can fiddle with the 220uf capacitors and the 470 resistors but they work the best. The robot should move about one inch a second towards the light for optimum performance, any faster it will miss the light any slower and you will get board real fast.If you have any question leave them in the comment box or email me at firstname.lastname@example.org.
