Outputs are latched. You have to explicitly set the pin to HIGH or LOW. It does not automatically revert after some period.

I think the term you are looking for is that you want the outputs to TOGGLE.

It is rather easy to do -

declare a variable -
int toggleVar = 0;

inside of loop(){
int ButtonVal;
buttonVal = digitalRead(ButtonPin)
if (buttonVal = HIGH ) toggleVar= !toggleVar;
if (toggleVar) {
digitalWrite(outputPin,HIGH);
else
digitalWrite(outputPin,LOW);
}
}

I don't guarrantee my code will run as written, but it is an outline...
