How to Install FTDI Drivers
Windows - Quick and Easy
By default, windows does not have FTDI drivers installed. If you plug in your FTDI, open the Arduino IDE, go to ‘Tools -> Serial Ports’, and see nothing, you need the drivers! Let’s go get them!
Download the FTDI Driver here.
Choose ‘Run,’ once it is has finished downloading, or find the file you just downloaded ‘CMD_v2.12.00_WHQL_Certified.exe’ and double-click it to run it.
Choose ‘Extract,’ and continue through the installation until it finishes.
If everything was successful, you should see some nice green check marks, indicating success! Note: You may need administrator privileges on your machine in order for this to run properly. If things didn’t work out, try the next section of this tutorial: Windows - In Depth.
Open up the Arduino IDE, and go to ‘Tools -> Serial Port’. If you now have a COM port, congratulations! Again, if something went wrong, either retry this tutorial or give Windows - In Depth a try!
