I am seeking to record weak electrical signals (up to 150mV with 0.1mV step) with Arduino. I think I have to use an LM358 op amp with 48k and 1k resistors but am not sure this will work. Can someone help?
These signals also come from different sources, do you think I can use one breadboard to record all datasets?
Also, if anyone knows what kind of test probes will be appropriate for these signals and about necessary components for this circuit that would be great.
Any help is appreciated!!!
