Really? I thought it was a 500ma max if it draws from a computer USB and 900ma if it took from a 9V adapter. Or rather, it would draw since there is no regulator as much as it could until something broke with 900ma being the general safety limit either in built to some arduino or just as a precaution.

edit: also why would I need resistors to bring down the current for the LCD? Why can't I directly wire them in parallel.
