Arduino Port Greyed Out

This tutorial will discuss a method to solve the port problem in Arduino IDE by installing the latest drivers for the Arduino board.

Fixing Arduino Port Problem by Installing the Latest Drivers

When you plug in the Arduino using the USB cable, a new device will pop up with a yellow icon in the device manager. Right-click the yellow icon and uninstall the already present driver. Now remove the USB cable and again connect it with the computer. Windows will install the required drivers automatically provided that an internet connection is available. If you have an Arduino that uses the CH340 USB chip on board, you need to install the chips’ drivers. Check this link to install the CH340 USB chip drivers. If there is another USB chip on board, you need to identify the chip and install its drivers. After installing the required drivers, the port will show up in the tools section of Arduino IDE.
