Thanks, Steve! It all started with your great design!
But, by the way... I'm having a tough time sourcing a few parts. I do already have 2 sets of the bluetooth modules (from you via Amazon), but I'm wondering if you or anyone has an idea where I can get the 3-wire passive piezo buzzers, the button matrix, and Dpad buttons? I've looked at Amazon, Sparkfun, and Adafruit. I have everything else, but those three items. Any leads?
Thanks!
