I am following this tutorial: http://www.cl.cam.ac.uk/projects/raspberrypi/tutorials/temperature/.
The problem is I don't have that specific temperature sensor on me. Since I don't have that specific sensor on me currently, would I be connect a potentiometer to an ADC and get similar results (obviously not getting temperature, but some kind of data I can play around with)? If I can't do that, what other possibilities are available?
