Autonomous Car

i was planning on trying to bring in an enable pin the other day but i thought that had something to do with the switch and knowing when it was on. are you looking at the schematic that i edited with the green Xs? because it shows the switch crossed out. otherwise i dont see anything around pin 9 i will but an enablePin(HIGH) im my program a little later this morning and see how things go.

thanks again newbie for all the help.
