The simplest is probably XBee. Once a module is configured, you just treat it like a serial port. The controller can transmit commands and all the pods will receive.

Re: Papa Soundie

Adafruit just posted a tutorial about that at https://learn.adafruit.com/microcontrol ... n?view=all. The DAC does ogg vorbis natively, so you might want to consider converting to that format as well.

Re: Papa Soundie

Stereo vs. mono could be an issue as well. The best thing to do is to check the test files and match their format in your production files.

SK6812 is a clone of the WS2812. You can use the Neopixel library to control them.

Re: No Response from Hardware (Hardware not Broken)

Also, your button will need an external pulldown resistor. Alternately, you can use the internal pullup and modify your program so that it is active low instead of high.
