hey. me again i know you must be thinking im repeating a topic i have already done.well i decided i dont want to buy the extra servo.i wanted my robot to see the obostacle then turn 90 dergrees to to the right or close to it.·and when i tried my program it would sometimes work then after a few turns it just started to turn as if something was there but nothing was. when my BOE was on 1 the ping sesor acted· fine ,i could tell by the led on it. now all does is turn. heres my program:

var··· word·· time
·strart:
·· pulsout x,500
·· pulsin x· time

·if time < x then forward
·if time> x· then right

· forward: pulsout 12,900
············· pulsout 13,600


· right:·····pulsout 12,900
············· pulsout 13,900·

var    word   time
 strart:
   pulsout x,500
   pulsin x  time
 
 if time < x then forward 
 if time> x  then right
 
  forward: pulsout 12,900
              pulsout 13,600
 
 
  right:     pulsout 12,900
              pulsout 13,900 

You don't have x defined and you are assigning it to a word and using it as a pin definition. Work further on your code. Do you have the downloads What is a microcontroller and the boebot download? If not get them, read them, understand them.

where it says pulsout and pulsin thats pin 15,and the if then commands are 500[noparse][[/noparse]top]499[noparse][[/noparse]bottom]also when i unplug my servo off pin 13 it acts ok,other servo pluged in but plug it back in it acts up again.also on the right: i have a delay in order to turn 90 degrees.i forgot what it was have not looked at it in a while.itried not having that but it would turn but once the ping got at an angle that it could see it went forward and crashed.

It's best if you attach the actual code you are asking questions about. Then we don't waste time trying to debug something only to have the poster come back to say, "that's not what I really have and your time was not helpful" Please ATTACH (see the choices when you post a reply) your code. The code you did give is still wrong!

ok i will get the exact code. this is not my computer so,you now. and i didnt know that option was there
tell me whats wrong? did you mean to do what i want is wrong or i wrote this code wrong.

You wrote the code wrong, get the downloads on the boebot, it has many code examples.
