user24309: I have a problem with the interworking between Atmel Studio 7 and Arduino IDE 1.6.10. 
I recently upgraded from IDE 1.0 to 1.6.10 and I can no longer upload my code to the Arduino. Everything works including compiling and it does recognise my COM3 port. Atmel Studio is configured for no external programmer.
When I compile with the Arduino IDE it does upload the code. My question is what goes wrong here, what do I need to do solve it. Thanks for your help
This the message I have in the end:
Compiling 'GridMonintor_V1R1' for 'Arduino Nano w/ ATmega328' Binary sketch size: 12,268 bytes (used 40% of a 30,720 byte maximum) (22.20 secs)

Minimum Memory Usage: 774 bytes (38% of a 2048 byte maximum) Uploading to I/O board using 'COM3'

avrdude: no programmer has been specified on the command line or the config file
         Specify a programmer using the -c option and try again

...Specify a programmer using the -c option and try again

For Arduino, the programmer switch must be -c arduino. The full arguments for avrdude, in the Atmel Studio 7 External Tools window, are:
-c arduino -p m328p -P COM3 -b 57600 -D -V -U flash:w:"$(TargetDir)$(TargetName).hex":a

See avrdude options.
