Hi gang... =)
I am waiting on a few things to arrive (as far as pre-made shields..etc)..
however I am curious if I can start playing around with .wav playback (even in a crippled or not great sound quality playback fashion)
I have odds-n-ends for components.. caps/resistors..breadboards...switches..etc..etc
I have soldered a 90 degree header pin to an SD card adapter so I can read my micro SD cards with/through it..
I have wired up the SD card as seen in most of the tuts/links here.. (using a resistor approach to logic/level shift the 5v to 3.3v for the sd card)
I loaded and use both SD library and the sdfat library.. both loaded and read card info (and all cards I tried) perfectly..
I loaded some of the sample sketches and ran them.. again.. everything seems 'fine'...
I would like to try and play a simple .wav file on the SD card with a button press (simple project goal)
However I have no DAC.. (never even used one before.. and dont know anything about them really)..
******(side note: if anyone has an average, no dual, common, breadboard friendly version of a DAC to recommend.. Id appreciate it for easier testing)
That being said..I do have some lm386 amps laying around still.. and a RadioShack amplified speaker... (or even a regular old hobby, non amplified speaker)
I guess Im asking for some pointers in the next direction to keep learning chipping away at this. (please no stupid or snarky comments..constructive help/comments please)
1.) where do I begin to read/play a .wav file from the SD?
I saw the wav shield page at Adafruit.. and found the waveHC library... (AF_Wav in your Arduino IDE >> Examples)
but it seems to have an OLD date? 2008? Still the (public) 'library' of choice for this?
Some help on what I need next to be able to hear the audio (at least in some fashion) would be appreciated and also any suggestions on code samples or newer libraries.
