HELP error message - school prject needs to be in for tomorrow!

I have uploaded the sketch and am getting the following message - can anyone help?

avrdude: ser_open(): can't open device "\.\COM1": The system cannot find the file specified.


Hmm you need to supply much more than that to interest anyone.

But chances are your Arduino is not on COM 1 maybe check in device manager first if its windows and then set the IDE to the CORRECT port.

Thanks both -sorry i'm only 10 and new to this - when I look on port it is greyed out?

I have gone to device manager and there is no 'ports' option to change to COM1?

If there are no other ports listed then its almost sure to be a driver issue. Search the forum for CH340 and start from there.

I am also going to refer you HERE, HERE

thanks for your help - will try to get better :-)
