I've been trying to connect my Arduino Uno R3 board to my laptop. I just updated today from the old IDE to version 2. Previously, I was able to connect the board to IDE 1.
I reviewed other threads from several years ago with a similar problem but couldn't fix my issue.
When installing the new IDE I accidentally clicked NO on one of the driver installations, I think it was ADAfruit? So, I believe that caused this issue. Where can I reinstall all the drivers that the IDE installation attempted to install?
When you plug in your Uno, does the serial port show up in the Device manager? If not, try another USB port, or cable. If it does, right click on the port and choose remove. Then unplug and plug in again. Is it visible in the Device manager now? Make sure there's no exclamation mark next to it. Will the IDE recognise it this time?
No, it doesn't show up in the device manager. Correct me if I'm wrong, but the fact that the Arduino LED is on means the cord is okay? I don't have another USB port on my laptop, but it worked earlier with the old IDE. I'm assuming it's because of the driver that wasn't installed.
Was that update on the same computer? Or a new one (or one where you re-installed Windows)?
If it was on the same computer, there would not be a good reason why Windows no longer detects it; any yellow triangles in device manager?
The installation process of the IDE includes the installation of standard drivers as used by official Arduino boards. If this was a new system (or existing system with Windows re-installed), there is one problem
You're not using the same cable as you used in the past or the cable is bad.
