Regarding the moderator comment "f you are seeing this:
avrdude: Expected signature for ATMEGA328P is 1E 95 0F
Then it looks to me that you do not have a '328P plugged in."
These are two new Unos purchased from amazon.com (different vendors). The chips on both are marked ATMEG328P-PU. Could they be counterfeit or clones? They were in nicely sealed packages and the boards are marked Made in Italy.
Also is there a way to determine the device code of a board? Thanks.
