Why Arduino Nano is not detected?
Well, probably two things: 1. The headers are not installed. 2. It uses a different chip (CH340G) for serial-USB communication than the others.
Why doesn’t the Arduino recognize the port?
If you don’t see an available serial port in the Arduino IDE after connecting your board and waiting a moment, you may need to install the drivers by hand.
Why is the Arduino Uno not working?
First make sure your board is powered on (green LED is on) and connected to the computer. Arduino Uno and Mega 2560 may have problems connecting to a Mac through a USB hub. If nothing appears in your “Tools > Serial Port” menu, try connecting the board directly to your computer and restarting the Arduino IDE.
Why won’t my Arduino connect to my computer?
What happens if the Arduino doesn’t detect power on the USB port?
A faulty USB cable can make your Arduino undetectable on your computer, not even detectable in your device manager, and can also cause frequent disconnections from your PC. If you find yourself in this circumstance, replace the USB cable that connects to your computer and Arduino board.
Why won’t my Arduino connect to my computer?
What if the USB port is not detected in the Arduino IDE?
Why is my Arduino board not working?

How do I know if my Arduino is fried?
Plug the board into a USB port on your computer and verify that the green LED power indicator on the board lights up. Standard Arduino boards (Uno, Duemilanove, and Mega) have a green LED power indicator located near the reset switch.
