ok, i designed a circut with a bs2, now im converting to a pic 16f84a,, originally i hoped to learn to use this programer i got online, with suplied ic prog, programing in hex, then i found pic basic,

ive managed to do every thing i need to basically except designate up to 4 input lines, basically im taking a signal sent to a servo,, jumping it onto a pic 16f84a,, apon an imput going high, it will cause the pic to run a sub routine till the servo is zero'd,

i need to know how to designate an io line to input,, and if im runining this input off of one of the servos wires, will i need to do any thing so the signal sent to activate the servo doesnt fry the chip,,
AND if i used the signal that causes movement in the servo,, will it draw enough curent off the servo to effect its operation,

if you havent guessed it im designing a pair of digitally activated turn signals for a remote controll car, to get away from switch activated ones that rarley work, 2 io lines for turn signals, and 2 for the brake lights, ( steering has a servo , as does the carborator) a few months ago i breadboarded this on a bs2, had it all programed,, just never actually made the conection betwen the servo and the bs2, can any of you veteran pic basic buffs tell me if my therory is sound and how to designate a pin to be input
