When I starting doing some research I found one hundred and one Simon games for Arduino, but I also found this link which used the LPC810.

This was appealing because I had never used the LPC810 micro controller, and this would be something interesting to learn about , however I had visualised something a little bigger and had already decided I wanted to use illuminated buttons from arcade machines to create a more faithful recreation of the original game.
The link also contained some schematics which would be the starting point for my design.
So taking inspiration from the Hartmut Wendt design I was ready to move on to working though my Electronics and Circuit Design covered in Part 3
