Arduino uno can't open device "Com 1"

Arduino : 1.6.8 (Mac OS X), Carte : "Arduino/Genuino Uno"

I have this error message... somebody can help me?

It says there is no COM1. Open the port list, is there another COM port listed? Then it's probably that one :wink:

Thanks you looks like one problem resolved... no more error message but now it doesn't play the song... just have a Biiip noise less than 1 second. Can you help me again :smiley:

Can you help me again

Without seeing the code and knowing anything about the hardware, doesn't seem feasible, does it?

Problem solved... when I unplug the USB cable to Arduino Uno,music stop playing like he doesn't keep the sketch in memory...everything turns off.

Still powered by 5v DC...But no led "ON" on the board!

I downloaded the sketch and save it.
