Im having problems blowing my code into my ardunino uno r3. Comes up with this message every time and nothing seems to get it to work. Any ideas?

Hello,

It sounds like AVRdude cannot find COM3. Maybe check the COM port number is correct in the project options and that nothing else is holding the COM port open. Unplugging and replugging the device may help and sometimes a full restart of Windows can be required.

Ive checked all the settings and everything is correct, shut down and restarted the PC and still having the problem?

Can the Arduino software program the device?

Maybe worth going into device manager, uninstalling the device driver and deleting it from your PC and then unplug/replug the device and installing the driver fresh. I've fixed a couple of COM port related problems this way though normally with cheap Chinese knock off devices.

It seems the official device driver detects the fake Chinese knock off hardware and disables itself, or it could just be me .

Ive tried deleting and reinstalling the driver and still hasn't helped. the Arduino uno im using is a genuine. As to using Arduino to blow in the code ive had a go but ive never used the program. When trying though comes up with an error aswell.

Hello,

Has the Arduino ever worked? Could it be faulty? Have you installed the USB driver from the Latest Arduino IDE? Flowcode 8 also comes with a USB driver you can try.
