Arduino Hardware Serial Port
Arduino ® hardware has serial ports, also known as UARTs, that can communicate with other devices that have serial interfaces. Hardware You can use serial port 0 to communicate with other devices that have serial ports, or to communicate with a computer over the USB port. How to Connect Arduino to a PC Through the Serial Port: To do that I have used a computer with Ubuntu 12.04 and the program language C, but if you want to used Windows the code works too, only have to change the port used to conect with arduino, but this is explain in the next step. This program is o.
Used for communication between the Arduino board and a computer or other devices. All Arduino boards have at least one serial port (also known as a UART or USART), and some have several. Serial communication on pins TX/RX uses TTL logic levels (5V or 3.3V depending on the board). Don’t connect these pins directly to an RS232 serial port; they operate at +/- 12V and can damage your Arduino board. Jun 18, 2016 The hardware serial is called Serial1 ('Serial' is a virtual USB serial port, it can only be used to act like USB-serial adapter to a USB host) The only things that can be plugged into the USB port and be expected to work are a USB host device like a computer (which will see a serial port), or +5v power (ex, from USB phone charger or something). Send Serial Data to Host Using Arduino Hardware: In this model, the Arduino hardware sends data to your computer over the serial port 0 (USB port) of the Arduino hardware. This model is configured to run in Normal mode. In this mode, the model is deployed on the Arduino hardware.
I bought an Arduino Uno recently. After getting the necessary cables, I decided to upload an example to the chip.
Instead of seeing that Blink, I received an error like processing.app.SerialException: Serial port 'COM1' not found. Did you select the right one from the Tools > Serial Port menu?
Yes, I tried that. But even Serial Port Monitor doesn't seem opening. Then again, I get some exception that isn't worth mentioning.
Arduino Uno Serial Port
After I found out that my Serial COM ports don't work (via Portmon.exe), and figuring out that I may even don't have any (there is no COM port in Device Manager), I also tried to download a driver for COM port, but it has also failed.
Some say that it's because of my Acer Aspire 5742's motherboard. Some say that the reason is Windows 7.
Long story short, I'd really appreciate if someone can help me with my COM port problem and mend my broken dreams.

Installing Drivers for Arduino in Windows 8 / 7.
( I tried it for Uno r3, but i believe it will work for all Arduino Boards )
Plugin your Arduino Board
Simply connecting the PC & mobile, you can conveniently use various features of SideSync. For a PC or MAC, click the download button above to install. For a mobile device, you can download the app from Google Play™ or Samsung GALAXY Apps which is preloaded on your latest Galaxy device. Samsung note 8 pc software.
Go to Control Panel --->System and Security --->System ---> On the left pane Device Manger
Expand Other Devices.
Under Other Devices you will notice a icon with a small yellow error graphic. (Unplug all your other devices attached to any Serial Port)
Right Click on that device --->Update Driver Software
Select Browse my computer for Driver Software
Click on Browse --->Browse for the folder of Arduino Environment which you have downloaded from Arduino website. If not downloaded then http://arduino.cc/en/Main/Software
After Browsing mark include subfolder.
Click next ---> Your driver will be installed.
Collapse Other Devices --->Expand Port ( its in device manager only under other devices )
You will see Arduino Written ---> Look for its COM PORT (close device manager)
Go to Arduino Environment --->Tools --->Serial Port ---> Select the COM PORT as mentioned in PORT in device manager. (If you are using any other Arduino Board instead of UNO then select the same in boards )
Upload your killer programmes and see them work . . .
I hope this helps. . .
Welcome
Did you install the drivers? See the Arduino installation instructions under #4. I don't know that machine but I doubt it doesn't have any COM ports.
Arduino Hardware Serial Example
No GrabbingNo GrabbingI've had my drivers installed and the Arduino connected through an unpowered usb hub.Moving it to an USB port of my computer made it work.
First: Sorry for my poor english (feel free to correct me).Abstract: Steps of How to resolve 'Serial port 'COM1' not found' in fedora 17.
Today install the packages for Arduino in Fedora 17.(yum install arduino) and i has the same problem: i decided to upload an example to the chip. and got the same error 'Serial port 'COM1' not found'.
In this case when i run Arduino programm, some banner appears which warns me that my user is not in 'dialout' and 'lock' group.¿Do you want add your user in this groups? I click in add button, but for some reason the program fail and not say nothing.
Step1: recognize the arduino deviceunplug your arduino and list /dev files:
plug your arduino and go and list /dev files
find the new file (device) that was not before pluggin for example:
ttyACM0 or ttyUSB1
Read this properties:
the first c mean that arduino is a character device.
user owner: root
group owner: dialout
mayor number: 166
minor number: 0
Step2: set your user as group owner.
If you do:
And you are not in 'dialout' and/or 'lock' group.Add yourself in this groups run as root:
restart the pc.and set /dev/ as your serial port before upload.
I hope be useful.Francisco.Bye.
3yanlis1bosunplug not necessary,just uninstall your port,restart and install driver again.you will see arduino COM port under the LPT & PORT section.
This fix / solution worked for me:Device Manager --> Ports --> right click on Arduino Uno --> Update Driver Software --> Search automatically for updated driver software
I restarted my computer and then opened the IDE again and it worked while none of the above did.
Maybe you have to do the things above as well, but make sure to restart the computer too.
