I'm building a monitoring package for a sensor via a raspberry PI and an ADC, which reads the analog signal (for the moment from a DC power supply instead the real sensor) and transfer it to my raspberry as a digital value. The problem is that the analog signals fluctuate a lot and as well the digital values. I want to measure the analog frequency via a python code and make a plot for it. But I don't know how to store those values in an Array and make a plot of that. Thanks a lot!
