Setting up Arduino


I have just downloaded Arduino 1.6.8 to my Mac.

I have a Mac OS X EI Capitan.

After downloading Arduino 1.6.8 i connected the Arduino board to my Mac via the USB cable but did not get any message indicating a new network interface was detected.

I assume it automatically picked it up - however, i did not see anything showing such in "finder"??

I then tried to upload the "blink example" to check if my Arduino board is working.

I got the following error message :

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

Sketch uses 1,066 bytes (3%) of program storage space. Maximum is 32,256 bytes.
Global variables use 9 bytes (0%) of dynamic memory, leaving 2,039 bytes for local variables. Maximum is 2,048 bytes.
avrdude: ser_open(): can't open device "COM1": No such file or directory
ioctl("TIOCMGET"): Inappropriate ioctl for device
Problem uploading to board. See for suggestions.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences

Can anyone help ??


You forgot the step where you select the Arduino from Tools->Port. Also be sure that the board selected under Tools->Board matches your model of Arduino.
