 We can download an squeak project and install it on our Sugar.

+Having executed our initiation script we have an squeak project with essential particularities in order to run our Arduino. Inside Electronics flaps we can find different tools.
- exec "/usr/bin/squeak" \
+But first we have to connect our arduino board, this is done in the following way,
-	-plugins "$EXE" \
-	-encoding latin1 \
-	-vm-display-X11  \
-	"$RES/Arduino.2.image"
- ''
-== Installation and use procedure ==
+*1) Connect the board to the USB port.
+*2) If the board doesn't have Firmata we have to upload it form [http://arduino.cc/en/Main/Software Arduino IDE].
+[[Image:Firmata1.png]]
+*3) To find out the serial port to which the board belongs we can go to Tools->Serial Port of a list we can always find the following:
+ /dev/ttyUSB0
+ /dev/ttyS0
-==Turtle Art==
-The code needed is located at (Thnks to Sayamindu Dasgupta)
+*4) Get an "Arduino board" from the Electronics flap, open its halo by right-clicking it, then open the Viewer by clicking the button that looks like an eye, and then find "arduino - connection" category
+[[Image:Arduinoconection.png]]
-*http://git.sugarlabs.org/projects/turtleart/repos/arduino-support
+*5) Select the desired port (i.e. "/dev/ttyUSB0")
-This uses the same [http://www.firmata.org firmata] protocol that the arduino-squeak connection uses.
+[[Image:Select-port.3.png|500px]]
-===Some use examples and screenshots===
+*6) Execute "Arduino board - connect"
+[[Image:ArduinoConnect.png|500px]]
+*7) Wait more or less two seconds  an then the  slot "is connected" have to change to  true.
+*8) After searching "arduino - digital pins mode" category and resetting the value of  "arduino board - is reading digital pins" (going from false to true). That's how the digital inputs are set.
+[[Image:True-falsedigitalpins.png]]
+*9) Now we are ready to use it!.

+==Turtle Blocks (Turtle Art) with Arduino Plugin==
+[[File:turtleart-arduino-palette.png|800px]]
+There are several efforts to develop Turtle Art support for Arduino.
+This implementation uses the same [http://www.firmata.org firmata] protocol that the arduino-squeak connection uses.

+The Arduino functionality was corrected from previous versions:
+* Analog and digital reading now works correctly
+* Auto detection of ttyUSBx port for FTDI device (Arduino board uses this for USB)
+It requires the Firmata protocol to be uploaded to the Arduino board.
+Use the latest Firmata version (2.1 as of now) downloaded from the Firmata page (firmata.org)
+The Firmata version included with the Arduino IDE has some inconsistencies.
+This version has english and spanish translations.

+The plugin file can be downloaded from [[File:arduino.tar.gz]].
