I just received my arduino uno kit from Mactrast with a complete course. The instruction booklet that came with it is from seeed studio. I am trying to install on my Macbook Pro OS 10.10.5   I have followed the instructions numerous times using the instructions in the course sponsored by UDEMY. Every time I try to download the blink program I get the following error message which means nothing to me. It refers me to the forum and I go in circles.

Problem uploading to board.  See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

I am obviously choosing something wrong but I have no idea what any of this means. Very frustrated!


Your IDE is from a different company. http://www.arduino.org/software
You need to ask them.

Here's the background on this.  http://forum.arduino.cc/index.php?topic=358657.0


Or download and install an IDE from arduino.cc ;)
If you understand an example, use it.
If you don't understand an example, don't use it.
