Turn ON LED when button is pressed and then released

abialevich1

How to write a program to turn LED ON when the button is pressed and let it ON when the button is released, and then turn LED OFF when the button is pressed and let it OFF when the button is released?

The code that I have bellow does not  work.

   BeforeStart

     OldButton≔ False 

     State≔ False 
//////////////////////////////////////////////////////

   Thread_2

     Button≔digital_in[2]

     LED≔digital_out[1]

     If (Button≟ True ) and (OldButton≟ False )

       If State≟ False

         Set DO[1]=On

         State≔ True

       Else

         Set DO[1]=Off

         State≔ False

       OldButton≔ True

     ElseIf (Button≟ False ) and (OldButton≟ True )

       OldButton≔ False

     sync()
