Hi, beginner here. I'm using a joystick to play Midi notes with an arduino and a Musical Instrument Shield (https://www.sparkfun.com/products/10587
) but the volume is too low. I want to be able to play over an acoustic guitar so I need a pretty strong sound.
It's so weak with just the shield setup and a speaker that I have to hold the speaker up against my ear to hear it at all.
At first I checked the internal volume, but I have the midi volume set at 120 out of 127. If there's any other way to increase the internal volume though I'd love to hear it.
So then I used this Mono Audio Amp Breakout board (https://www.sparkfun.com/products/11044
) powered with 5v and a 8 ohm, 0.5 watt speaker to amplify it some. Now I don't need to hold it against my ear but it's still very weak. I'd like it to be as much as 10x louder then it is now with the small amp.
Does anyone have any ideas on how to increase the volume dramatically or a suggestion for a good amp to build that wouldn't destroy my circuit? Nothing too crazy, I am a beginner after all. Also, could I hook this up to a regular guitar amp or would that cause a problem?
Thanks for the help!
