Olivier��What are the topcis you investigated?did you contact the authors?STefHi,Since some weeks, I do some experimentations with an Arduino board. I search now to use my Arduino with Pharo. I have found some informations on the web but nothing seems usable or up to date for the latest versions of Pharo.��Someone have worked on this domain ? I'm interested by a firmata client protocol or why not a solution to program an Arduino directly from Pharo.Best regardsOlivier ;-)--Using Opera's mail client: http://www.opera.com/mail/
