Help me, I'm a Nube.

e14 Contributor

Hi All,

 

I am new to the Arduino.  I want to control 3 processes all from an SD card attched to the Arduino.

 

  • Turn the output source on and off
  • Sync this "on and off" with trigger points in audio soundtrack that also plays from SD card and sends to onboard speakers
  • Spray a mist every few minutes
  • Change the card which will have new sound trigger points and audio

 

Please help with this list . . .

  1. How do I add an SD port onto the Arduino
  2. How do I program the SD card
  3. How do I get the Arduino to read the different SD cards properly

 

And lastly, is it even possible?

 

Thanks!!

    You don't give quite enough detail about your apploication to give any definite advice but it looks as if you would like to read data and audio files from the same sd card. There is a  sparkfun board to help do this which is a bit different form a standard SD card interface because it has the audio file playing chip.

     

    I'm not sure how you mean to add trigger points to an audio file - it might be simpler to keep the trigger points in a separate file as time offsets form the start of the audio file.
