Hi,I'm very new to electronics, specifically physical computing.my first real project I'm trying to take on is to build a weather station.I want to hook up my humidity sensor (HH10D), and through the reading that I've done it seems that is communicates via I2C. my question is should i be using a resistor(s) when connecting it to the Arduino pins?
The Wire library, which does the I2C communication, enables the internal pull-up by default. However, they are very weak (30-60kOhm). So for relatively short runs, they'll work fine.
The I2C gadget on the other end usually has pullups, too...
