I'm a newcomer in arduino and want to test my nano-board making blink light,
but it doesn't work.
my settings:
board: Arduino Nano
processor: ATmega328
port: COM3
programmer: AVRISP mkII
Disconnect the Arduino Nano board and close Arduino IDE.
Connect the Arduino Nano, wait a few seconds and start the Arduino IDE. When you select the COM port in the menu, do you see the COM port ?
Did you install the drivers ? You can check the Device Manager of Windows.
