Arduino UNO and Mega Windows 7, 8, 10 USB driver Solved

If you're using an Arduino UNO-compatible board and your PC doesn’t recognize it via USB, you're likely missing the correct driver. This tutorial shows you step-by-step how to fix the USB driver issue in Windows 7, though the same method applies to Windows 10 and 11. This is especially useful for CH340 or other clone boards which don't work out-of-the-box with the default Arduino drivers.

The tutorial walks you through downloading and installing 7-Zip, a free tool used to extract the driver files. Once 7-Zip is installed, you’ll be guided to the correct driver download link, how to extract the files, and finally, how to install the driver through Windows Device Manager by pointing it to the extracted folder. You’ll also see how to recognize whether your system is 32-bit or 64-bit and choose the correct driver accordingly.

After installing the USB driver, your Arduino board should appear under COM ports in the Device Manager, and the Arduino IDE will be able to upload code to your board without errors. This tutorial is crucial if you're using low-cost clone boards that don’t include official FTDI or Atmega drivers and require CH340/CH341 or similar USB-to-serial chip drivers.

This step-by-step process is easy to follow for beginners, and watching the video ensures you won’t miss any detail. All software links are provided below the video. If you’ve been stuck with “USB not recognized” errors, this guide is the fix you need.
