Basic Audio Playback with Arduino

[SLagerZahne]

Is it possible to connect external ram/rom for audio?

[mipmipmipmipmip]

what if you use an SD card reader...

[iToasterman]

@mipmipmipmipmip u have to know how to read a partition... and ntfs is out of the quistion...

Make the video longer so I can rap to that beat. :P

[molinobeer]

are you a rapper?

[Louisdagod3]

Maybeh

[alexinwunderlander]

so can you loop the audio by some function?

[alexinwunderlander]

hmmm, is it possible to loop it with a function?

[littlescale]

Yes

[thebarkpetition]

How is it that you can be so awesome, always?

[3yE]

It's pretty trivial. For a better demonstration of basically same hardware (ATMEL 8-bit uC and an R/2R resistor ladder DAC) i suggest you look at v=_uU4BzSQQmY

[littlescale]

I know it's trivial. Duh. It's an example for a class, nothing special at all.

[molinobeer]

How do you did that?

[alexinwunderlander]

cool! It needs to be longer though..

[littlescale]

yeah, but the arduino only has ~ 30KB of program space :( - so this sound file is 29.5 KB in size.

[molinobeer]

hey, can you explain me how the analog inputs wok? Do they measure voltage or amperage? is possible to build and ohmeter with an arduino?

[nil0bject]

@molinobeer anolog uses PWM. it turns a analog signal to a digital wave. google "arduino org pwn"

[molinobeer]

@nil0bject

That's the analog OUTPUT, not the analog INPUT, but thanks anyway, also as been a while since I made that question for which I already know the answer. Thanks

@littlescale couldn't you hook up an sd card to your arduino?

[nil0bject]

@ZouloumOSX yes
