I would be deeply grateful for any help you can offer, I have scoured many other forums for fixes but none have worked.
My Arduino Uno turns on, however, I'm having trouble uploading sketches to it. I have attempted to upload a blank sketch, it hasn't worked, any other sketches I try, compile fine, but when uploading, it comes up with the error message:
avrdude: ser_open(): can't open device "\.\COM5": Access is denied.
I have the correct board selected in tools and the correct COM port selected. I have used a USB 2.0 rather than a USB 3.0. I open my code files from the arduino IDE rather than from file explorer. I have nothing connected to tx and rx pins. I have tried pressing the reset button before uploading and used the technique where you connect the rx pin to ground. I would be really grateful for any help.
Thank you!
Do a FULL restart on your computer. (POWER off and back on)
No idea where you saw the connect Rx to GND! This is wrong.
Thank you, will try that now.
Thank you so much! It's working now.
