There are one or two members of the Arduino community that don't seem to tolerate 'noobs' (god I hate that term) and can be downright sarcastic ro rude, but thankfully they are in the minority. But most of guys on here you will find to be very tolerant and helpful, as long as you provide them with the correct information regarding your query.
Just don't expect people to write the code for you as a) You'll learn nothing and b) You might get a rude reply.
