Using a potentiometer as an analog sensor on the RC is easy. Connect one end of the pot to the red wire (+5), the other end to the black wire (GND), and the center/wiper to the white wire (SIG).
I think you'd get somewhat better results with a 20K or even 10K pot. The lower resistance will resist picking up noise on the signal.
