It seems we have a lot of newbies lately. This website is here to ask questions and get answers however, there seem to be a lot of questions popping up that sorta shouldn't be asked... Here's what I mean:
If you are new to electronics or robots or programming don't ask a question about step 487 when you know nothing of step 1, 2 or 3. Again, if you are new to this don't even think about motors or sensors etc. YOU NEED TO START WITH A BLINKING LED, period. Baby steps, folks!
