I'm trying to create a simple sequencer which sets the volume of an audio input. It doesnt amplify the signal at all, just varies the resistance on the audio signal to reduce the volume.
The circuit has 8 pots with an LED underneath each. The LEDs light in sequence. When each LED is lit, the resistance changes to the value of the pot above.
I've written a PIC program to send an output to 8 pins in sequence which lights the LEDs in sequence, but I'm not sure now I link this to the audio wave. Any ideas? Thanks for your help.
