Again.....Group,

This is the third time I have asked this, and I would have
gave up if I did not know that SOMEONE could help me out here! All I am
trying to do is hook up 4 bump switches to A BSX with two Futaba 148 servos.
I can not seem to get the code right for it. I have got it to do any BUT go
left or right when my robot hits a wall!! If any body knows ANY THING PLEASE
send it my way.... I will for ever appreciate it if some one could clue me
in on this!!?? Thanks (IF some one replys), in advance (again). -Alex Burke

    Alex,

    I'd suggest you look at the robotics code posted on the
    www.stampsinclass.com site. They use IR sensors to do the same thing. Your
    code should be very similar since the IR sensors they use have digital
    outputs.

    When faced with a problem, the best thing to do is divide it into pieces:

    1) Can you spin the servos?
    2) Are you detecting the switches (use DEBUG to see)
    3) Put it all together.

    If you'd post your code, my guess is someone could spot your problem. You
    may also have a hardware problem. Remember:

    If the servos are back to back, you spin them in opposite directions to get
    forward or backward motion. Spinning them the same direction gets a turn.

    Make sure you are not resetting the Stamp when you turn the Servo on. If you
    have an LED hooked up to an output pin (say P15) try:

    TOGGLE 15
    PAUSE 1000
    TOGGLE 15

    at the top of your code. Then if that light blinks, you know you did a
    reset.
