Upon any audio being detected I want the LED to light, fairly simple I hope! I am going to plug this into a headphones output. Editted to add: Im a complete novice at this, would appricate any help including circuit diagrams, components etc... I can manage the soldering, just Thanks mhm Last edited: Aug 6, 2010
