I had an idea of a speaker playing a song as soon as I open the gate of my garage. I made some notes but I still couldn't figure out how it will work.
These are the objects I think could make this possible:
- Battery Snap to barrel plug, so I can power the Arduino Uno:
- MicroSD Card Module, so the Arduino can get the Music:
- Male to Female jumper wires, so I can connect the MicroSD Card module and other modules:
- Trust Ziva USB Speaker, to play the sound:
- USB Module, to connect the speakers to the Arduino Uno:
- 3.5mm Audio Jack module, to connect the speakers to the Arduino Uno:
I don't know a lot about the Arduino so it might help explaining in detail if somebody is willing to help.
USB speakers require a USB driver (Typically running under Windows, OS-X, or Linux). And, the UNO is a USB device (like the USB speaker) not a USB host.
Your best bet is an audio shield (https://www.sparkfun.com/products/12660). (Maybe that's what you have... Your image doesn't show-up in my browser.) They come with various features, but they all have a memory slot, a sample-rate clock, a DAC, and all of the necessary firmware, etc., to "make sound". The Arduino is just a "master controller", and in some cases the audio shield can work without a microcontroller.
An audio shield will work with regular (analog) powered computer speakers, or with an amplifier and speakers. Or, some audio shields can drive a passive 8-Ohm speaker (at low power).
