How to amplify the output of my Arduino Music Shield
October 7, 2014 2:19 PM Subscribe
I bought this sound shield off ebay.
After finding the right library. I can make it play mp3s, but I can't make it very loud. I plugged in my computer speakers and turned up all the way it's just not loud enough, not nearly as loud if i had plugged it into my phone or computer. I also tried plugging it into my old stereo amp and i could get it pretty loud, but for my application I really need desktop speakers.
Is there is easy way to boost the signal, is that even what I want to do? This is where my understanding of electronics wear thin.
Response by poster: They're powered in the sense that they plug into the wall, yes. The same speakers are loud enough from a computer, but like half the volume off the shield.

Best answer: It looks like there is a volume adjustment on it - have you turned that up? If the output signal is too low you won't be able to raise it enough with your speakers to get a good level
