From code you can use process.exit([errorcode]) where [errorcode] is an optional integer (0 is the default to indicate success).

If you're using the Read Eval Print Loop (REPL), you can use Ctrl + D, or type .exit

Install arduino-ide

1. Download the latest packages, Linux 32-bit or Linux 64-bit, from the official link below:

Don’t know your OS type? Go and check out System Settings -> Details -> Overview.

2. Open terminal from Unity Dash, App Launcher, or via Ctrl+Alt+T keys. When it opens, run below commands one by one:

Navigate to your downloads folder:

cd ~/Downloads

Decompress the downloaded archive with tar command:

tar -xvf arduino-1.6.6-*.tar.xz

Move the result folder to /opt/ directory for global use:

sudo mv arduino-1.6.6 /opt

3. Now the IDE is ready for use with bundled Java. But it would be good to create desktop icon/launcher for the application:

Navigate to install folder:

cd /opt/arduino-1.6.6/

Give executable permission to install.sh script in that folder:

chmod +x install.sh

Finally run the script to install both desktop shortcut and launcher icon:

./install.sh

In below picture I’ve combined 3 commands into one via “&&”:

Finally, launch Arduino IDE from Unity Dash, Application Launcher, or via Desktop shorcut.
