Instructions:

1. Downloaded IDE

Download link: http://arduino.cc/en/Main/Software (copy and open)

2. Download the USB chip driver


3. Plug in the NANO development board, the driver will be installed automatically

4. Select the board NANO in die

5. Select the COM port, this can be queried in my computer, the port in your uno development board just now


6. It is best to choose first, the routine program that comes with arduino, burn it in
