Input Disable Untill Point in Program

hey guys, i need a little advice on getting and input to go high, then disable its self untill a serial command is given to enable it again????

sounds simple enough for one of you experts!!

:D :D :D :D

As with your other thread about relays that I read the question is difficult to understand. An input will not "go high", rather an external signal will make it high. What is it that will take the input high ? A switch maybe ?

Can you please be more specific in your requirement.

As Bob says, it sounds all garbled. Sounds like an XY problem http://xyproblem.info/

Good point, Mike.

@NZarduino - why do you want to do this?

… then disable its self untill a serial command is given to enable it again???

Just ignore the input, eh?
