Hi,QuoteSee http://sound.westhost.com/project53.htm which has a great way to control volume from one of the arduino's PWM outputs The circuit on this page is a volume-limiter. It is used to protect to your speakers from overloading (or in other circumstances) for changing the dynamic of an electric guitar. You can't control the volume with this circuit.Eberhard
Umm can't control volume with a circuit that controls volume?
what planet are you from? just hook the led to pwm with an rc filter instead of the peak detector...
