Incorrect port selected. Select a port from tools -> port menu; it's got COM4 selected (which presumably you used previously), but it's saying that there is no COM4. Windows will often assign a different port number depending on which USB port a device is plugged into (and occasionally for no apparent reason), so you just need to select the correct port.

Hi,

I had the same problem and i just went to Tools+Port, and then selected the one that showed Arduino Genuino/UNO, in my case (i switched from port 13 to port 20).
It worked.

Regrads,

@kmspavan

Just posting the error message is useful but it would be better if you included any other info such as the board being used and any additional components you may have connected.

Might I suggest you read the posts at the top of the forum section too please.

plz help I dont know what the problem is

RandomStuff:
plz help I dont know what the problem is

Remove any connections to pins 0 and 1. These pins are used for communication with your computer, including uploads. Connecting anything to these pins can interfere with uploads.

Make sure you have the correct board selected from the Tools > Board menu.

Make sure you have selected the port of your Arduino board from the Tools > Port menu.

Sometimes the port will be labeled with the board name in the menu. Other times it will not. If you don’t know which port is your Arduino, you can find it like this:

  • Unplug your Arduino board from the computer.
  • Tools > Port
  • Note the ports, if any, listed in the menu.
  • Close the Tools menu
  • Plug your Arduino board into the computer.
  • Tools > Port - The new port listed in the menu is your Arduino board.

I'm getting the same error while uploading the code to the board.
I'm new to this and I'm just trying to follow what instructables has put up.
the error message is :

Sketch uses 21624 bytes (67%) of program storage space. Maximum is 32256 bytes.
Global variables use 910 bytes (44%) of dynamic memory, leaving 1138 bytes for local variables. Maximum is 2048 bytes.
avrdude: ser_open(): can't set com-state for "\.\COM4"

SO what does this mean?
What is the second method of uploading the code? How to do it?
How to resolve this?
Thanks in advance.

Try restarting your computer. Sometimes the COM port will get stuck in a bad state and the restart fixes that.

Hi Guys

I know this thread is pretty old, but I thought I should add what I found since all the above suggestions did not work for me.
What ended up working for me was changing the programmer (Tools > Programmer) from AVRISP mkII to ArduinoISP, then the sketch was able to upload without any errors. Then I changed it back to AVRISP mkII and it still worked. Not sure why or how this happened. Might be worth trying if none of the other solutions worked for you.

Thanks for your time and I hope this helps you out. I really do. I know how frustrating this problem is, first hand.
