I am a complete newbie when it comes to the arduino and I am trying to grasp the power of what it can do. My understanding is it can send tones to a speaker. I read the threads where SMB theme song can be played through a series of tones. My question is can it play full songs? Can you load a song into its memory and have it be triggered by each opening and close of a switch? I have the ethernet adapter and it has a place for a micro sd slot or a mini , can it be loaded from there to the speaker?
I bought the 8ohm speaker from radio shack, and I was reading about installation and it said hook up through a 100ohm resistor, the starter kit came with 220ohm resistors. My final question would be the higher number for resistor thats more power going to the speaker?
Thank you and I appreciate any insights.
