This little lovely dropped on the doormat today from Adafruit.
A little late for ArcHak, but it will hold a special place in a project I'm working on at the moment. I'll write some more about that soon.
The WaveShield can play audio at 22KHz from an SD card and has a socket for headphones and provision for connecting a speaker. The audio data is clocked out of the SD card by an interrupt handler in the Arduino, so the device can also perform other tasks while audio is being played.
