Hello,
I would like to have a Little help with a Project i'm making.

I need to read the signal of a second order low-pass filter to the serial plotter in the Arduino IDE.
The problem is a have concerns about how enter the signal; I just put the output of the circuit into the arduino and program the Arduino to read the signal?

I'll be greatful for any kind of help, thanks.
Can you send the Arduino program used for this project . We are currently working on something similar

Welcome to AAC!

There's nothing to it. You just do an analogRead() on the analog pin your signal is connected to. Just make sure the voltage is in the supported range. If it's too low, amplify the signal. If it's too high, attenuate the signal.
