I'm trying to create completely DIY EMG. As many of you may know, I will be dealing with microvolt inputs. I know that op amps amplify voltage, but I am wondering if I can somehow get a 1,000,000x amplification. Do I need to create my own op amp by soldering a few components or are there already op amps available that can do this?
Note: I am amplifying voltage in order to have the signal be read by an Arduino Uno.
