Makes sense. I'll start from the get go.
I've been developing on an uno and for my first project I've been working on a GPS navigation system. I have all the GPS stuff working; it gives me my distance and all the data I need etc... So, to take this to the next level, I wanted to build a flash front end to save a destination using google maps. I've seen some of the flash+arduino integration tutorials through the playground, but so far all the tutorials I've seen are either using the NETLab or teach you how to turn a light on and off.
The idea of parsing a byte array and converting the data back into a data structure the arduino can use is a bit daunting for me at the moment. I figured how to parse floats with this tutorial:http://www.mikechambers.com/blog/2010/08/01/sending-multibyte-numbers-from-actionscript-to-arduino/
But beyond this, I wasn't sure how to identify the data as one type of variable or another (does that make sense?). I will say that I just found this library (aJson), which looks really promising. I can build a json object from flash or any web service without any issues. http://interactive-matter.eu/how-to/ajson-arduino-json-library/
