Overview- I'm making a bank of analog sine wave oscillators and I'm interested in keeping the design compact. I've started by making a Wien Bridge oscillator. As I'm working from a single power ...
I followed the mic + op-Amp part of this schematic exactly using an Lm386 chip: https://randomskk.net/projects/lightstrip/schematic.pdf and sent the output from the op-amp into a pin on an Arduino ...
I want to create a sound amplifier with the LM386 and I need a potentiometer. I don't have a clue what I'm doing (:P) but I've printed out the datasheet (for the LM386) and had a look at it. So I ...
