This article mainly introduces how to choose the port in Arduino, the article is very detailed, has a certain reference value, interested friends must read it!

2.4.4 Select Port

After selecting the board, we need to select the port where the board is connected to the computer. It is also set in the tools menu, as shown in figure 2.42.

Note: the COM1 port is usually the serial port that comes with the motherboard, so it is usually not the port on which the LilyPad is located. The port number is not fixed, and under the Windows operating system, the number can be seen in the device manager, as shown in figure 2.43.

Under the Linux operating system, ports are named differently from Windows, as shown in figure 2.44.

Under the Linux operating system, you can view the port name through the dmesg command:

Arduino-1.6.0$ dmesg

[51608.798450] usb 2-2.1: Product: FT232R USB UART

[51608.798453] usb 2-2.1: Manufacturer: FTDI

[51608.798455] usb 2-2.1: SerialNumber: AL00DUXU

[51608.807806] ftdi_sio 2-2.1 1.0: FTDI USB Serial Device converter detected

[51608.808028] usb 2-2.1: Detected FT232RL

[51608.810892] usb 2-2.1: FTDI USB Serial Device converter now attached to ttyUSB0

You can see from the last line of output that the FTDI USB Serial Device converter now attached to ttyUSB0, the LilyPad programmer, is attached to the ttyUSB0.
