hi everybody!
I am trying to create a circuit that will blink a strip of LEDs (requiring 18V) to the beat of a song using a microphone input. I figure i need an adjustable low pass filter as i only want the LEDs to react to the low frequency beats but still want to be able to "tune in" on the correct frequencies. I would also like to run the circuit off of a 3V source. I figure the basic circuit would be:
preamp>mic>adjustable low pass filter>amp(to 18V)>LEDs
As a programmer i have a fairly limited knowledge of circuits but I still know my way around a soldering iron.
Can anyone tell me if the above circuit would work? and how i could go about designing it?
thanks.
