Project 3, Coding Exhibition

I have decided that i am going to do the If/else function for my Project 3
My Metaphor which i am going to use is:
Think if the If/Else function as a light switch. If the switch which the light is attached to is pressed then the light will light up. And if the switch isn't turned on then the light will stay dark

My first Idea for the Exhibition (which could change from now until the time when we have to hand it in) is to have a model set up with a lamp attached to a large switch like the image underneath. and when the switch is pressed the light will go on otherwise it will stay off
