    Arduino 16-bit 500SPS Dual Channel DAQ

    Thank you for asking!So regarding the script, if you installed Anaconda Python, you should be good to go. If you only installed Python separately, then I recommend opening a Command Prompt window (search on google how to do that if you have no clue what I'm talking about) and write:pip install pyserialHit Enter and PySerial should be installed. But you will need other libraries as well: numpy and matplotlib. You could google how to install each one, but why not remove your current python installation and install Anaconda Python 2.7? That should take care of any library issues.I recommend that you open the Python script with a text editor and check that you have the proper COM port set (see Step 12).Regarding the RTD, I have no experience with it nor have any idea how to wire it.

Try to dig some more on the interwebs. But to answer (a part) your question: The AIN- ports are already connected to the GND (if you did your soldering right) internally in the ADC. That's why in Step 9 I only connected the middle potentiometer pin to the AIN1+. But you should certainly connect the GND from the RTD to the Arduino GND.
