Hi,
I'm facing a potentiomenter reading issue. I've been able to get stable readings by isolating and grounding cable and pot and also calculating average readings. But whenever I connect an HC-06 bluetooth module to my project the pot readings become unstable again 
Could you please point me to the possible problem?
Many thanks!!!
It is most likely a hardware or software problem. Can't see either. Read the forum stickies to see how to format and post your code. Post a schematic of your project. My first guess is that there is a power problem, but without further information that's it.

How? You've not given any useful information. Go and read the "how to post" sticky thread.

Maybe getting too large voltage fluctuations on the power supply rail. Try putting an electrolytic capacitor (eg few hundred microFarad) between the arduino 5V pin and arduino ground pin.
Thank you for your answers. I will try putting this electrolytic capacitor. Other thing I could try is to change the power supply from USB to 12 V to see if that cahnges anything.
