== Choose a larger font ==
Switch to the GNOME desktop. This is because the application has been tested with GNOME, and not with Sugar.


The default font is very small on the XO laptop, to fix it:
=== Packages ===

In Terminal:

sudo yum install -y arduino

Roughly 40 MB of packages are downloaded and installed.

=== Fix Access ===

The IDE requires that the user be a member of the ''lock'' group. See also <trac>11972</trac>.

This fix also restarts GNOME, so that the membership change is effective. <!-- todo: test to see if this is actually necessary -->

In Terminal:

sudo groupmems --group lock --add olpc && \
sudo systemctl restart prefdm.service

=== Choose a larger font ===

The default font is small.

== Firmata ==

Firmata is a generic protocol for a computer to communicate with microcontrollers. The Sugar Labs [http://wiki.sugarlabs.org/go/Activities/TurtleArt Turtle Art activity] included in OLPC OS builds supports Firmata 2.1 or later, and can use an Arduino board as a general purpose analog and digital I/O interface.
