Now that the buttons are working I'm excited to make this project into a wearable suit, specifically a Halloween outfit. I modified the wiring to begin to imagine how it will work with buttons on the fingers of a glove that connect all the way down to the Arduino somewhere in a pocket on the shirt. So I put the buttons on one breadboard and all the resistors and 5V and ground connections onto a separate board. The idea is the buttons can be isolated up on the fingers of the glove and all the resistors will be on a board right next to the Arduino since that will need more space than the finger of a glove. So here's the prototype for that setup. The next step will be putting it all together on a shirt!
