Hi, First of all, amazing work you have done and thanks for sharing. a couple of questions... 1.- I've bought a USB host shield and I assume there's no need to connect 5V/GND/TX/RX since is connected on top of my UNO R3 (I have zero arduino knowledge) however is not working trying to make the increase/decrease feature, below a picture of my board. drive.google.com/open?id=1s4ZNzk7mx6u-9huYBMI5tWeBHG-c8t_62.- Could anyone share a photo of any project on the protoboard, I think it could help some of us with little to zero knowledge. Below is the video showing what I want to accomplish. www.youtube.com/watch?v=c_eHqE3xl0w Thank you all

I can't see any pullup resistors on the switch circuits. Are you using the internal pullup feature on the Arduino? I used 12k resistors as that was all I had spare, but values aren't so important.
