Okay, so I got an Arduino Uno. And I wanted to test it out. I went to Arduino IDE and went to examples and selected "Blink". I then clicked upload and I got the following error:
avrdude: ser_open(): can't open device "\.\COM1": The system cannot find the file specified.
You need to select the serial port of your Uno from the Tools > Port menu. If it's not on there or if it's grayed out then you may need to install the driver for the Uno.
sir, iam using arduino Uno, the problem is that, it is showing onlu one port , COM1, and boards arduino/genuino Uno. ian dont know does it means. i cant find COM1 in in my system. when i plugged srduino , in device manager it is showing COM4, or COM6 or 7. but here in software I have only one option COM1 . what should i do?
you said "You need to select the serial port of your Uno from the Tools > Port menu. If it's not on there or if it's grayed out then you may need to install the driver for the Uno."
how to install drivers for Uno
yes I tried . that yellow triangle is gone . but while uploading to board i got this
