I wish to couple two units that function as a light organ:
The first is a microcontroller that plays an MP3 file. The output is a line signal meant for a headphone or something similar.
The second unit is a discrete circuit using a simple microphone that picks up sound and steers the light intensity of a lightbulb accordingly.
While the µ-controller runs on 5V DC the other circuit runs directly on 230V AC (without any galvanic protection)
My problem is that the microphone also picks up ambient noise from people talking.
First question: Can I just remove the electret condenser microphone and put the line signal to it?
Second question: what are possible solutions to solve this?
Thanks in advance!
