Australian Delphi User Group is looking for speakers for their annual conference the ADUG Autumn Symposium to be held around March/April 2013 and all travel and accomodation expenses are paid for by ADUG... this is my submission video showing how to use Delphi to develop an iOS app, call a DataSnap REST server and send UDP messages to an Arduino board in order to turn on and off a lamp by clicking a button on my iPHONE! Nice hum?! If you like it, please support this video by clicking "like", following me on twitter and letting ADUG know that you want to see this how-to demo on their symposium next year! :)
