hello guys, I'm from Greece, I just learned some stuff about arduino from a friend of mine and I find it really amazing
I want to get started and learn more about arduino, I have been coding for some years in C programming language but I know nothing about arduino, what's the best way to get started?
You haven't told us what you want to do with it. PaulS had the right points in his reply above. Tell us what projects you would like to do before we can advise you more.
i want to start from simple things implementing everything that is sugested in the tutorials and then maybe use my imagination to create other things too
Assuming you have done Blink and some of the serial stuff - Shift registers extra IO for your pins, little cost. I would do a binary counter on them first. Then maybe move on the making programs for a GLCD, as you are a programmer I don't think that programming will be the issue...
