Im building a toy and needs some music and sound. A simple pwm to a speaker is ok but i would like some better quality if possible. I found some really cool shields but way over kill for my project. I did find some older 80's chips - 8 bit music chips for $4-5, but they appear to need extensive support. I also realize i can use pwm to simulate a sin wave, but my toy has a bunch of other things to do and i dont want to dedicate it to music. So my question is, can i get some better music than a square wave?
