Hello,
I have been plagued for the last couple of days on how I would be able to amplify the voltage from an Piezoelectric buzzer or an electric drum pad so that when it is struck an array of LED's will light up.
I tried op-amps (but not sure If I had it set up right), transistors, and an audio amplifier but neither seem to work...I feel as if I built and rebuilt every circuit you can build to do this.
I don't know if I'm missing something with these circuits of just am building the wrong kind
Please if anyone can help me with a schematic that will take the input signal voltage with a peak between 200mV to 1.7V and amplify it to a voltage that would be able to drive an array of 4 LED's (Shown Below) I would be extremely grateful.
Or if not just a direction as to what IC I can use such as an op-amp or audio amp that would do the thing I want.
