I am trying to get my AQI set up and get the following error when uploading v 6.0, any ideas please

Arduino: 1.8.2 (Windows 10), Board: "Arduino Nano, ATmega328"

Sketch uses 16720 bytes (54%) of program storage space. Maximum is 30720 bytes.
Global variables use 1106 bytes (54%) of dynamic memory, leaving 942 bytes for local variables. Maximum is 2048 bytes.
avrdude: verification error, first mismatch at byte 0x0000
         0x00 != 0x0c
avrdude: verification error; content mismatch
avrdude: verification error; content mismatch

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.
Thanks
Jim
