Make a light turn off one second after I let go of the button

dougp:
Your description is a bit unclear. "I am trying to make it so that when I press the button it turns off..." This means it was already on. "...when I let go of the button it will turn on and then turn off after one second..."

So, is this a one time event or, is there a next time for pushing the button?

there is a next time for me pressing the button
