    How can I build a sound controlled LED circuit without a programmed chip?

    Do you think I could connect that amplifier circuit to the circuit I posted previously, with the LM339 operational amplifiers, instead of an LM3914/5?

    How can I build a sound controlled LED circuit without a programmed chip?

    Hello. Yes, that is what I am trying to make, it is however, not a school project. Thanks for your suggestion, I found a circuit though that'll do the trick. http://www.discovercircuits.com/PDF-FILES/voltst1.pdf" The only problem I have now is that I don't know how to connect the electret...

    How can I build a sound controlled LED circuit without a programmed chip?

    Hey. I am currently working on building a circuit that should receive sound input from an electret mic, and then based on the output voltage, light up a certain number of LED's. For example, if the sound is low it should light one LED, and if it's very high 3 LED's. I imagine that 3 LED's total...
