How to connect the QTR 31A to Arduino

I would like to connect all 31 sensors to the same Arduino (line follower)
How can I sample all those analog outputs ? Is there a board that can do that?

Can you recomanned for an ADC that I can use?


We do not have any experience with it, but this Sparkfun Analog/digital MUX Breakout board might be an easy way to go if you already have an ADC on your MCU and just need more inputs. We would love to hear how it works for you if you try it!
