I am Trying to make a MicroSD .wav file player using Arduino Uno. I have ordered a MicroSD Card Module from ebay today.
As You can See in the Product Image, there is not mentioned on the PCB that which Pin Is ground or VCC Or any other SPI pin. 1. How will I identify the correct pins of the MicroSD Module ? 2. How can I connect a speaker to arduino to play .wav files. Is Amplifier neccessary? I am weak when it comes to electronics.
I have listened that when I connect a Capacitor in series with speaker, it will boost the output volume. There will not be music but only voice recordings in .wav files. I want to listen it clearly only.
