Hello,
I built an audio amplifier with the LM386. It works.
I have a circuit with a microcontroller that controls an mp3 player with two 8 ohm speakers with functions of Play/Next/Reset. It works.
I connect the amplifier to the circuit through a jack. My reset function stops working.
Now my reset function simply sends LOW then HIGH signals to the mp3 player, shutting it off completely and turning it back on.
I believe the amplifier connected to the circuit is keeping my mp3 player ON through the aux/jack. I'm not sure if thats possible.
I've even tested it with two seperate power supplies.
Anybody have any input how to solve this problem?
