<em>"Daddy, daddy, how does a computer work?"</em> We're used to say that curiosity is a bad habit but it is nonetheless one of the greatest strenghts of kids: they are eager to learn. Learn how a computer works, how one can build an application for a phone or a tablet, how one can create a video game. The best answer is probably to give them the tools to discover by themselves the answer to those questions. Eclipse is used by hundreds of thousands of adults for programming activies, so why not by kids? How to turn Eclipse into a programming environment for kids? This talk will present our approach and thoughts to simplify the Eclipse user interface for usage by kids. We will show how we created, thanks to <a>Sirius</a>, an easy-to-use and natural graphical tool to let kids discover programming. A demonstration will present a prototype of a development environment that allows to program an Arduino using a simple and graphical block-based language.

1. TURNING ECLIPSE INTO AN ARDUINO
PROGRAMMING PLATFORM FOR KIDS
Mélanie Bats / Obeo

2. CURIOSITY
Explore, question and learn

3. DISCOVER BY YOURSELF
Explore to understand cause and effects.

4. COMPUTERS ARE EVERYWHERE
To understand the world, you need to understand how
computers work

5. UNDERSTAND ELECTRONICS
Play with sensors and actuators

6. OPEN HARDWARE

7. ELECTRONIC FOR KIDS
Open hardware dedicated to kids learning electronics :
littleBits

8. ARDUINO

9. ARDUINO KITS
Cheap, easy to find thanks to many different providers :
AdaFruit, DFRobot, SeeedStudio, SnootLab, ...
So many kinds of modules available!

10. UNDERSTAND PROGRAMMING
Many open source software are dedicated to learn
programming to kids : Scratch, TurtleLogo, KidsRuby,
Python4Kids...
Initiatives : Programatoo, Devoxx4Kids, greenlight, coding
goûter...

11. TEXT

12. GRAPHICAL

13. PROGRAM THE REAL WORLD

14. ECLIPSE IDE FOR DEVELOPPERS
Complex UI, concepts (perpsectives, project lifecycle...),
languages (Java, C)

15. TURNING ECLIPSE AN IDE FOR KIDS
Graphical programming & light UI

16. A SIMPLIFIED UI
No menu, only a toolbar with 4 buttons activated according to
what is possible

17. DASHBOARD
The process :
1. Define connection between hardware platform and
modules
2. Describe the sketch
3. Upload on the target

18. HARDWARE
Platform, Modules, Wire

19. SKETCH

20. PROTOTYPE BASED ON DFROBOT ARDUBLOCK
KIT
Sensors : ambient light, infrared , sound, push button, rotation
Actuators : LEDs, micro servo motors, fan

21. HELLO WORLD
Blink a LED!

22. GRAPHICAL BLOCK-BASED LANGUAGE
Structures : while, repeat, if
Functions : delay
Hardware modules : Status, Level, Sensor
Variables
Constants
Mathematical operators

23. SIRIUS
A tool to quickly define DSL based custom multi-view
workbenches with dedicated representations
Sirius

24. WHY USING SIRIUS ?
For the tool development phase : Dynamic & iterative (live)
development
For kids : Tooling adapted to the development of arduino
small projects
