Arduino installation on Linux Mint is easier than going to sleep (at least, it is to me). On a DSL/ISDN connection, you should be ready in no time.
su -c 'apt-get install arduino' root
installs the Arduino IDE. Enter the root password when prompted and accept the installation.
This allows you to communicate via a serial port (which should follow the format
x is a number arbitrarily assigned by the system). Type:
su -c 'usermod -aG dialout <username>' root
where <username> is your username.
This is optional, but quite simple. Type:
and you should see something like
If not, repeat the previous step. Or try logging off and then back on, so that the usermod command can take effect.
Plug in your Arduino board. Open the Arduino IDE in the GUI and click Tools -> Serial Ports -> /dev/ttyACMx. Unless you have more than one serial device plugged in, there will only be one entry in the list to choose from.
Congratulations! You're ready to go!
The accepted convention is to use
sudo requires you be a member of the
sudoers group. (You could also edit the supplementary files the sudoers file reads from, but this is highly NOT recommended.)
su without the
-c option will not accept a command to pass to the root shell, but will instead login to the root account. This can be dangerous, so I recommend using
su -c or (if you're already a member of the sudoers group or have an administrator handy)
