If you can't find it here, you can check Adafruit, Sparkfun, or the Arduino.cc website (if you're using Arduino) for info on parts you want to use.


Couldn't find an MP3 shield at Adafruit, but here's info on their .WAV shield:

You might get some more help if you tell us a little more about the hardware you plan to use in your project.

i am not talking about shields i am talking about reading the file and playing it manually with the mcu

I just went to Google and typed "pic16f877a MP3"...

Actually, I got as far as "pic16f877a MP..." before the autofill gave me two choices;

  • pic16f877a MP3
  • pic16f877a MP3 tutorial


I recommend you check out this site....


Chris the Carpenter calls it "The Googles" but most people just call it "Google."


In all seriousness, this post is handwritten for you...

What to do when you have a project idea but don't know where to start

Since you already have a microcontroller you can skip to Step #2 and apply that methodology to your problem. 


To show I'm a good sport I provide you this link which I got from a page found by following Step #2:


edit - Note how it says:

BEGINNERS BEWARE! This is an upper-intermediate project. You will need things like a PIC programming device and some working knowlege of C and/or assembly language programming, as well as a decent but not huge amount of electronics experience. An oscilloscope doesn’t hurt either. Be warned! It’s an involved project to say the least!

Sometimes people save the audio files to an EEPROM. Searching for "pic16f877a audio eeprom" yields...



These should get you started.
