I want to control my tv (led) with a voice frequency. If it reaches a certain frequency i want the tv to turn on and so forth. Why wouldn't I have a relay. basically your saying i don't need a relay? I don't really understand the schematics how did they determine the component values. Can you help me in this matter?
