The DHT sensor, LCD and Nano all operate on 5V logic. The Ethernet shield does not operate at 5V, but rather at 3.3V.
Does the Nano have a way to connect the two, will they work anyway (probably not), or should I use a CD4050 that is recommended on adafruit?
Any guidance is appreciated; I'm still amazed in what $10 in parts can do.
Also, in regards to the DHT22 sensor, what do I need in terms of a resistor? I've seen some people say you absolutely need a 4.7K resistor on the data pin for "pull up", and others who say it's unnecessary. Can someone give a definite answer, either way?
Edit, wrong link on my nano clone.
