Hi people, im new and I apologize in advance for my English.
To put it simply, what I would like to do is, with arduino, a board similar to the isd1820 sound recording module, but without the recording part. What I would do is put the sound file through the Arduino.
How do you think I can do this?
Thank you very much
I couldn't find a datasheet for the ISD1820 chip but it looks like you can't write digital audio data to it.
If you search for "Arduino Audio Shield" you will find add-on boards that can play MP3 files (or WAV, etc.) from an SD card. You have to use your computer (with an SD reader/writer) to write the audio file onto the SD card.
These boards do all of the "work" and the Arduino just works as a controller to select the sound file, start/stop, and adjust the volume, etc.
Some of these boards can directly drive a speaker and others need need an amplifier.
