Scroll down and click on ‘Windows ZIP file (for non-administrator install)’ to download.
When the download has finished, unzip the file to the computer hard drive.
Connect the control board to your computer using a USB cable.
Wait for Windows to begin its driver installation process. After a few moments, the process will fail, despite its best efforts.
Open up the Control Panel.
Navigate to System and Security. Next, click on System. Once the System window is up, open the Device Manager.
Look under Ports (COM & LPT). You should see an open port with the name of your control board and a port to it locking like this:‘(COMxx)’. If there is no COM & LPT section, look under ‘Other Devices’ for ‘Unknown Device’.
Right click onthe item with the name of your control board and choose the ‘Update Driver Software’ option.
Next, choose the ‘Browse my computer for Driver software’ option.
Finally, navigate to and select the driver file named ‘arduino.inf’, located in the ‘Drivers’ folder of the Arduino Software download (not the ‘FTDI USB Drivers’ sub-directory). If you are using an old version of the IDE (1.0.3 or older), choose the
Uno driver file named ‘Arduino UNO.inf’
Windows will finish up the driver installation from there.
