2. Next we had to make the light a button: If you didn't select the light you couldn't turn it exactly in to a button. You have to make sure that you are in the button and not in the frame, because it won't make it into a button for you to click.
3. Next you have to signal the car to move and to stop: If you do not make sure you are in the right frame than you could choose the wrong frame.
4. Creating the reset button: You click text and write Reset, then you also make it a button. The same as #2 if you don't make sure you selected the button it will not create the button for you.
