Topic: first upload isn't working, "Serial Port COM1 not found" (Read 13763 times) previous topic - next topic


I keep getting this error when trying to upload
I have the correct board selected: Arduino Uno
however, it's not letting me select my serial port.

i'm using windows 7.
has anyone had this similar problem?
I would appreciate this very much


COM1 is almost never the correct port - my Windows XP using using COM4 for my UNO.

I have to ask since you did not provide any details - have you followed instructions such as:




i haven't no.

thank you so much for pointing that out to me


I have the same problem as the following:
( I have to reboot PC, and use it a while, it happens again, basicly I could not do my normal work)

It simple says port not found. Are you sure you select the correct port?
