Magician,
I need help.
I'm trying out your Pitching Code.
I connect my function generator in A0 without any Op Amp, I mean directly.
Then I got a bad signal in the out (I did the circuit that you put in the blog, the one who has to connect pin5 and pin6 with some R and Capacitors)
Do you know what could be ? Do I doing something wrong?
In the out I connected a USB Spekaer which has an Amplifier.
Thanks
