* [[Arduino/1.0.5|Arduino 1.0.5 on OLPC OS 13.2.8]],
== Ingredients ==
* an XO laptop with OLPC OS [[13.2.0]] already installed,
* [[Arduino/1.8.5|Arduino 1.8.5 on OLPC OS 13.2.8]].
* access to internet,

== Recipe ==
* switch to the Gnome desktop, as the software works best in Gnome,
* start the Terminal application, and type this:
:<pre> sudo yum install -y arduino</pre>
* wait for the download to finish, it should need roughly 61 MB,
* start Applications -> Programming -> Arduino,

== Testing ==

* connect Arduino board,
* choose Tools -> Board entry, e.g. Arduino Uno,
* choose Tools -> Serial Port entry, e.g. /dev/ttyACM0,
* choose File -> Examples -> Basics -> Blink,
* choose Upload to send the program to the Arduino board,
* see LED flashing.

== 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, and can use an Arduino board as a general purpose analog and digital I/O interface.

The StandardFirmata may be uploaded to an Arduino board, using the Arduino IDE:
* start Applications -> Programming -> Arduino,
* connect Arduino board,
* choose File -> Examples -> Firmata > StandardFirmata,
* choose Upload to send the program to the Arduino board.

Alternatively, StandardFirmata may be uploaded without using the Arduino IDE, see [[ProtoSnap_Contributors_Guide/Upload|How to upload StandardFirmata using ino]]. The download size is much smaller (18MB), but the steps required are more complex.

== 12.1.0 ==

Follow the [[#Ingredients|instructions above]], but before starting Arduino add the ''olpc'' user to 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, type this:
sudo groupmems --group lock --add olpc && \
sudo systemctl restart prefdm.service

Installing the Arduino IDE on OLPC OS.

Choose a larger font

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

  • Applications -> Programming -> Arduino,
  • File -> Preferences,
  • Editor font size to 18, OK,
  • Quit and restart Arduino.
