    Why the urgency? Strong trees take time to grow. Good solutions are created after the seeds germinate.

    I recommend you familiarize yourself with the Finite State Machine coding technique. It makes it much easier to initially code and then to debug your code when it fails to operate as you intended.

    Here is just one explanatory link to the technique. There are hundreds of other links that can be found on the Web.
