Error While Uploading
I am using Windows 10 and i am not able to upload the code, i have followed all the steps properly.
This is the error i am getting

Make sure your Arduino port is selected properly as the error message shows port does not exit.
Also, make sure that while the small window showing connecting..... message, the pin needs to be grounded
