Interfacing Flex Sensors for new users

Hi Guys! I'm totally new with arduino and circuits. However, I'm looking to learn more and I need your help.

I'm looking to add 2 or 3 flex sensors to Arduino board and I want the Data to be sent real time to my laptop to read resistances of different bending motions.
Can you suggest what I should purchase?
Would the starter kit have everything I need?
Do I need a special driver and software to read in data from the Arduino board? ( I would prefer a CSV file that I could analyze using Matlab)

Any Help would be much appreciated. Thanks in Advance

Hi- welcome to the Arduino forum.

Two separate questions there I guess:

I'm not sure if starter kits include flex sensors, but in any case they're available at places like adafruit. To hook it up is easy: it's one side of a voltage divider so all you need is another resistor and some wire. It's conceptually no different from reading the analog voltage from the wiper on a pot; as shown here. Note you won't be measuring the resistance as such, but that can be calculated from the equation for a voltage divider.

I have little experience about getting data into the PC, but Processing is probably a good place to start: that's exactly what its for.
