Hello everyone. I’m having a hard time with: avrdude: ser_open(): can’t open device “\\.\com3”: the system cannot find the file specified, but I’m not sure how to fix it.
avrdude: Version 6.3, compiled on Jan 17 2017 at 12:00:53 Copyright (c) 2000-2005 Brian Dean, http://www.bdmicro.com/ Copyright (c) 2007-2014 Joerg Wunsch System wide configuration file is "C:\\\\Program Files (x86)\\\\Arduino\\\\hardware\\\\tools\\\\avr/etc/avrdude.conf" Using Port : COM1 Using Programmer : arduino An error occurred while uploading the sketch Overriding Baud Rate : 57600 avrdude: ser_open(): can't open device "\\\\\\\\.\\\\COM1": The system cannot find the file specified. avrdude done.Thank you.
I’ve discovered the root of your problem after hours of investigation. Errors in programs can be caused by three things:
1. Because you disabled the section – “show verbose output during compilation”, you’re seeing this Arduino problem.
2. Arduino do not upload and show the error: “ser_open(): can’t open device.COM1”. The kind of this error is arduino port error.
3. You haven’t made any decisions about the board’s configuration.
You must select a board name as well as a port number.
Go to tool section top menu -> select a name for the bulletin board “which mention on your board”, and the port sections will be highlighted automatically. Select one of them and check building and uploading the code; you should observe successful results.
You may notice this successful text in your compiler after you’ve uploaded your blinking code.
Check the led blinking code after you’ve configured these options.
If you follow my advice, you should be somewhat be able to solve your problem quickly. Best of luck!!!
