changing states

christo27

I have a program that when push button is pressed it will flash some lights I need to change the program so when it is pressed again it stops the flashing lights any help?
here is the code so far

' {$STAMP BS2}
' {$PBASIC 2.5}


DEBUG ? IN11, CR

DO
DEBUG "WAS BUTTON PRESSED",CR
IF IN11 = 1 THEN GOTO BLUE_LIGHT_ON
LOOP


BLUE_LIGHT_ON:
DEBUG ? IN11,CR
IF IN11= 1 THEN GOSUB TRAFFIC_FLASH

TRAFFIC_FLASH:

DEBUG "BUTTON PRESSED",CR
DEBUG? IN11, CR
DEBUG "TRAFFIC FLASHING",CR

HIGH 11
HIGH 4
HIGH 2
PAUSE 700
LOW 4
LOW 2
PAUSE 700
IN11= 0
RETURN

christo27

pIN11 = pushbutton
pin 4= led
pin 2 = led

I realized a mistake I was trying to keep a led on when PB was pressed and that high 11 was keeping it lit but doing this would never cause pin 11 to go low again any help?

You are "falling through" into traffic_flash when it returns.
