My very first codeprogram

How old is it?

Sadly I can't tell for sure.

1. This Button script may be the oldest according to my memory.
   I am not 100% sure tho.

2. This series circuit for an LED array however has a older last-modified-date.

3. According to this picture, which got last modified on Wendsday the 09.09.2015 7:17PM,
   my first script must defently be older than that.

What do I believe now

I believe I had my first lesson on C++ on Monday the 7th of september. We learned how to turn an LED on and of and the script I used there is lost.
We probably got some homework after that lesson. A array of LED's makes much more sense to tackle first instead of the functionality of a button.

So this series circuit is probably the first code I have ever written on my own.
I would determine the date of creation on Sunday the 13th of september 2015.
