I have a project that utilizes tone() and also PWM of an LED strip. I am getting 'interference' when the speaker is playing a tone that is consistent with the flash of the leds. I figured this was a conflict issues. I got the toneAC() library which I think utilizes a different timer for the audio. That fixed my problem. However the two pin set up of toneAC may be a problem as I need to amplify to a 12v speaker.
So how do I enable the ability to change the timer used for the speaker like the toneAC library does. Or would it be more simple to try and keep toneAC and amplify it. Im just not sure how to amp a two out put pin setup like toneAC requires.
PS and yes I do have capacitors its definitely a timer issue.
