The unregulated pins for the servos are on the bottom left, while the regulated for the sensors are on the top left. You can probably follow that the south power rail is unregulated while the north is regulated. I"ll try to get back to any questions you have about my setup if you have them. Listen to rgcustodio, what he said is exactly what is wrong with your layout. Holes on a breadboard are not independent. *I didn't realize there was built in attachments on these forums, i was trying to use picasa web albums and was having issues :/
When i tried turning on the power, my batteries got really hot. Is that a problem? lol Cheesy
(even if it's a joke ,) Do not turn on the power until you're sure the circuit is right!!! As soon as you connect two nodes at different potential together, you'll get a short-circuit! And it's easy to make that mistake if you don't know how a breadboard works...
A bit off topic . . . but I wanted to comment on the breadboard that airman posted:http://www.societyofrobots.com/robotforum/index.php?topic=2964.msg21713#msg21713Although this is the typical wiring of a board, it is not a rule.I've found myself using several boards that do not have this wiring, and wasted tons of time until I figured out the wiring in the board was whack . . . for example, the power buses on it were not connected! On some boards I found AC voltage signals jumping between rows . . . and on some there were manufacturing errors where holes that should have been connected were not . . .
