Electronic applications and the Arduino
Published in Mike Tooley, Electronic Circuits, 2019
If your port doesn’t appear, try restarting the IDE with the board connected to the computer. On the Mac, the serial port should be something like /dev/tty.usbmodem621 for the Uno or /dev/tty.usbserial-A02f8e for older, FTDI-based boards. On Linux, it should be /dev/ttyACM0 or similar (for the Uno) or /dev/ttyUSB0 or similar for older boards. On Windows, it will be a COM port, but you’ll need to check in the Device Manager (under Ports) to see which one. If you find that there’s no serial port allocated to your Arduino board, you will need to check that you have the correct driver installed. In the case of Arduino, the drivers work by providing a virtual serial port (or virtual COM port). The Arduino Uno uses the standard USB CDC drivers that are normally provided by the operating system. These drivers allow the host computer to communicate with the ATmega8U2 on the Arduino board. Some other Arduino boards use FTDI drivers to communicate with an FTDI chip on the board (or in the USB-serial convertor).

COM port (communication port or serial port) is a serial communication interface through which information can be transferred sequentially one bit after another. It is different from the parallel ports which can transfer multiple bits at the same time. COM ports enable serial communication between a serial device and a PC. Whenever you connect a serial device to a PC, it assigns a COM port to the serial device for communication. To know the COM port assigned by your PC to the connected Arduino Uno board follow the below steps.

Arduino IDE have facility to program a supported device by serial communication through USB using CP210X USB to UART bridge. It creates a virtual serial COM port in a computer. The COM port corresponding to the connected device can be verified at ‘Device Manager’ in a Windows machine as shown in a Figure 4.12.
In-ear-EEG – a portable platform for home monitoring
Published in Journal of Medical Engineering & Technology, 2020
The microcontroller board not only controls the amplifier and the ADC, but also connects SPI and USB buses. Serial communication over USB using FTDI drivers, which are included with the Arduino software, provides a virtual COM port, which facilitates the implementation of an interface between the system and software on a smartphone or a computer.
