My code is not uploading to Arduino Uno, Please help!
First of all find out on which port the Arduino is connected by running the command : dmesg | grep tty. You should get [82893.921017] usb 1-1: cp210x converter now attached to ttyXXX with the ttyXXX COM port.
Then check if the port is visible Tools-&gt;Port. If the port is not visible then you have a permission issue.
