Speedtest using python kivy

Question

I wrote the back end of a speed test and now I am trying to make a graphical user interface that dynamically shows the fluctuations in a speed test on a gauge until it gets the speed. But I couldn't, I just made it in a static way for now. any suggestions to make it? and I want to make a loading effect too when the speed function is searching for the best server. any ideas??

You will need to put the speedometer needle in its own Image, then use Rotate to set its angle. Something like this:
