Use Serial Communications with Arduino Hardware. Arduino ® hardware has serial ports, also known as UARTs, that can communicate with other devices that have serial interfaces. 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. Using the Hardware Serial Ports The Teensy boards have 1 to 6 hardware serial ports, which may be used to connect to serial devices, like GPS receivers, XBee & ESP Wifi modules, Modbus controllers, serial interface displays and many other serial devices. 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.
Software Serial Example
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. In this example, the baud rate of Serial 1 baud rate is set because the TX1 and RX1 pins correspond to the Serial port 1 of the Arduino hardware. If you are using any other serial port pins for communication, specify the baud rate of the corresponding serial port. Click OK to close the dialog box.
Arduino and Genuino boards have built in support for serial communication on pins 0 and 1, but what if you need more serial ports? The SoftwareSerial Library has been developed to allow serial communication to take place on the other digital pins of your boards, using software to replicate the functionality of the hardwired RX and TX lines. This can be extremely helpful when the need arises to communicate with two serial enabled devices, or to talk with just one device while leaving the main serial port open for debugging purpose.
In the example below, digital pins 10 and 11 on your Arduino or Genuino boards are used as virtual RX and TX serial lines. The virtual RX pin is set up to listen for anything coming in on via the main serial line, and to then echo that data out the virtual TX line. Conversely, anything received on the virtual RX is sent out over the hardware TX.
Hardware Required
Circuit
There is no circuit for this example. Make sure that your Arduino or Genuino board is attached to your computer via USB to enable serial communication through the serial monitor window of the Arduino Software (IDE).
The software is best known for its detailed scan as it can locate unidentified drivers which are usually not detected by the default Windows Device Manager. The database of Device Doctor includes almost all major hardware device manufacturers and currently has drivers for more than 13 million devices and PCs.TIP: Read our. Microsoft driver updates for windows 10. Device Doctoris a free software for Windows PC which scans the computer hard disk and checks if there are some new updates available for the drivers.

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.
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
Go to Control Panel --->System and Security --->System ---> On the left pane Device Manger
Expand Other Devices.
Therefore helps you to share your connection with home and office. You also share the connection with your friends without any hesitation. Your friend catches the signal in the long distance while their connection works very well with this tool. Just one click step and in one second your connection will be shared.It creates a router and its single length is too much longer. https://cosmeticstree523.weebly.com/wifi-connectify-free-download.html.
Arduino Hardware Serial Port Monitor
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 ) Trackmania 2 stadium free download.
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. . .

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.

I'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.
Unique features. Nexus 1 vst free download. Proc & Conc.
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:
Download iphone apps to pc. You can to restrict, block, or allow in-app purchases. Learn more.The App Store isn’t available on Apple TV (3rd generation or earlier).
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.

Arduino Hardware Serial Port Number
unplug 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.
