*************
The last part of this script adds the current user to the 'dialout' group. This
is usually required to use serial ports and communicate with the Arduino. You
must logout and login again before this will take effect.

It's also possible that your distribution uses a different group. If you still
can't communicate with the Arduino after logging out and back in, attach your
Arduino and check the group that owns it. Then, add your user to that group if
you're not already a member.
