Hello every one
i am trying to turn a led on, off· wiht···a ·signal to the same i/o
one time for on one time for on· and so on.
Could you·please help, ·so·far i got· this

if in0 =1 then
high 5
pause 1000

else if in0 = 1 then
low 1
pause 1000

end if

loop

Your IF statement doesn't really make sense. The ELSE IF will never be triggered since it has the same condition as the IF statement preceding it. I think that this is what you are trying to do:

LedControl var 0
LED var 1

Start:
DO
IF LedControl = 1 THEN
HIGH LED:
PAUSE 1000:
ELSE IF LedControl = 0 THEN
LOW LED:
PAUSE 1000:
ENDIF
LOOP
END

This will change the LED's status (on or off) depending on whether or not PIN 0 is high or low.
Could you please explain your problem?

Firts thank you for replying

i am sending a high signal to the stamp to turn the led on

then another high signal again to turn it off and another high signal

to turn it on again, and so on i am trying to turn led off and on

with the same high signal to the same i/o over and over again.

The you need something more like this...

LOW 1
Start:
DO
    IF IN0 = 1 THEN          'Check for P0 to go HIGH
        TOGGLE 1               'TOGGLE Output pin P1
        PAUSE 1000            'Pause for 1 second Debounce
        DO WHILE IN0=1     'Wait for P0 to go LOW (Release)
        LOOP 
        PAUSE 1000            'Pause for 1 second Debounce 
    ENDIF
LOOP
END
