Com ports

Using Arduino Programming Questions
#1

Hey everyone i am new to arduino

I just want to ask that how can i add com ports in the arduino app

I want to add com port 3 and remove com port 4

#2

Why do you want to do this?

#3

I am making an obstacle avoiding car

So i wanted to upload the coad in that is there any way to add com port 3 its downloaded in the device manager

#4

That doesn't explain why you want to "add com port 3 and remove com port 4". Look, we're here to help you, but we can only do that if you provide us enough information to work with.

I want to add com port 3 to upload the coading from com port 4 its not getting uploaded

So i want to know that how can i add com port 3 in the arduino app

#6

on the Arduino IDE, under the Tools menu item, the port option allows the port to be changed

is this what you're looking for?

If you dont mind can you send it with pics☺

Still, I have no clue what you are trying to accomplish. I'm going to give you one last chance before I give up on helping you.

Spend some time writing a DETAILED explanation of what you are trying to do.

Now, pretend you are someone else, who only has the information you have provided on this forum thread. Read the explanation you wrote. Does it make sense? Is there enough information? If no, then work on it more until it's good enough.

You're assuming OP does.

See like you have sent photo in the port option there are many ports like com port 1, com port 254 and com port 255

There are multiple ports but in mine port option there is only one port which is com port 4 so how can i add on com port 3 in the port option??

I hope you understood

Windows assigns ports. There is nothing you can do in the Arduino IDE to "add" port options.

Try this:

  • With the Arduino board unplugged from the USB open the Tools > Port menu and note the listed ports. If the Port menu is gray and disabled then that means there are no ports available.
  • Close the Tools > Port menu.
  • Plug in the USB cable on the Arduino board
  • Wait a little while for the Arduino board to connect
  • Open Tools > Port, the new port on the list is your Arduino board. In some cases it will have the name of the board next to the port name but this doesn't happen with all boards. If the Port menu is gray and disabled then that means your Arduino board didn't install correctly. You may need to install a driver.
  • Select your Arduino's port from the menu.

If COM4 appears after you plug in your Arduino board, then your board is on COM4. Just select Tools > Port > COM4 and get to having fun with Arduino.

If no new port appears after you plug in your Arduino board, then you have a problem. It could be that you haven't completely plugged in your USB cable. It could be that you need to install a driver. It could be that the board has been damaged. It could be that you have a bad USB cable.

“but in mine port option there is only one port which is com port 4 so how can i add on com port 3 in the port option??”

A com port is usually established when a serial device is connected to your computer (windows). If a com port is not established for that device when connected (does not appear in Tools > Port), then the previously mentioned issues are probably in play. Are you trying to connect a second/different board to your computer?
