I am having a hard time with Arduino's analogRead() on multiple pins at once. I am having cross intereference, so I'm considering a change in attacking the problem.
What about using an i2c a/d converter and let Arduino read the data over a 2 wire connection? I'll save some pins (I am going to read several analog signals anyway, my Uno does not provide enough analog pins) and will hopefully get no cross interference, will I?
Does anybody have any suggestions about a cheap and easy to purchase i2c a/d converter? I'm not looking for 16bit resolution, a 12bit res will be enough (in some cases even 6bits will suffice).
