I have updated the programming and buttons on this prototype. Thanks to our class feedback and The Laws of Simplicity by John Maeda, I decided to make the programming of sequences easier and with less steps. Now someone can walk up and push a button to start programming a sequence, wait 2 seconds to input that sequence and wait another 4 seconds to save the entire sequence. The prototype saves the last two sequences, with a pause in between sequences.
I also worked on the buttons to make them easier to press. The metal washers were not working consistently, so I made yet another trip to the hardware store and found some black rubber washers. These are good because they provide support all around the bottom of the button and contract a little bit to give a “push” feel to the button. I also backed up the pcb board with some wood pieces to support the board so that it does not break.
Check it out in action. The quality is crap cuz I am using a little web cam that has auto focus, so thats why it is annoyingly zooming in and out.
