I spent a few sessions communicating to Andres what I wanted to achieve for this project and how we could design the hardware / software around that idea. 

This was his very first board, and it was the perfect stepping stone for a quick project iteration. If this were golf, we hit the green with the first shot. He would probably ask that you do not pay any attention to that pink cable there, though. 

A few interesting things we learned here:

• The first buttons in the top area were too small and not practical. 
• The pcb would work, but it was not efficient in terms of area usage
• Sensors worked!

All in all, very good feedback and insights. All the basic functionalities are there, so this allowed him to start programming, and I went back to the drawing board in search of the ideal form factor and more efficient PCB arrays.
