Hi guys, I need to design a circuit capable of activating a light if there's a sound source.
Sound= Light on
No sound at all = Light off
Here's an attempt (see attachment). The AC voltage source is simulating an audio source. Then i converted it to DC so it could activate both transistors shown in the figure. Wich wouldl then activate a Relay that would activate an AC light.
Please tell me your feedback about the circuit, and I got a question as of how the circuit could affect the output signal (as in noise and etc).
Any feedback is good, thanks!
