 Bigger Bigger  Smaller Smaller  Reset Reset

Hi guys,

I'm relatively new to Arduino and would really love some help with a project I am working on for a school project.
I am wanting to modify Karl Klomp's 'Cheap and Dirty Video mixer' ( - attached below...

*brief description of Klomp's mixer: basically merges the two RCA video signals proportionally to the degree the potentiometer has been adjusted to, to create a new,merged video output.

What I want to do is to replace the potentiometer with a sound sensor so that the degree of the video merging is proportional to the amount of sound that is registered as an input. If anyone can provide any help (especially diagrams) at all I would be very, very grateful!

Many thanks in advance!
