    Hello Cordcole,

    What code/circuit are you running? Your board could be resetting due to a short somewhere in your circuit. With more information, we can definitely help you pinpoint your problem.

    the code is
    ' {$STAMP BS2}
' {$PBASIC 2.5}

DO
     DEBUG ? IN0
      IF (IN0 = 1)THEN
Counter         VAR     Word

DEBUG " counterclockwise 10 o'clock", CR

FOR counter = 1 TO 30
  PULSOUT 1, 1000
  PAUSE 1
NEXT

DEBUG " counterclockwise 10 o'clock", CR

FOR counter = 1 TO 30
  PULSOUT 2, 1000
  PAUSE 1
NEXT

DEBUG " counterclockwise 10 o'clock", CR

FOR counter = 1 TO 30
  PULSOUT 3, 1000
  PAUSE 1
NEXT

DEBUG " counterclockwise 10 o'clock", CR

FOR counter = 1 TO 30
  PULSOUT 4, 1000
  PAUSE 1
NEXT
   ENDIF
   LOOP

    This is a program that once a switch is triggered for servos go off for a short amount of time

    Your pause time is too short and should be closer to 20 rather than 1

    Hello Cordcole,

    are you using an original parallax servo?

    My hobby servo shows the same effect, but if I play arround with the value of the pulsout signal (set it lower than 1000), i can fix it.

    How do you have the button wired? It's possible you're creating a short, which will drain any 9-volt pretty quickly. Do you have a volt-meter? Hook it up to measure the current being drawn from the battery -- it should be 5 mA or less, unless the Servo is moving, where it can jump to 750 mA.

    Usually, I don't recommend driving a servo with a 9-volt battery -- a 9-volt usually can't supply that much current because of "internal resistance" in the battery.

    no the switch was not connected but i just figured out how to fix it. I reprogrammed the basic stamp which seemed to work.

    thanks who all helped me turn.gif
