Choosing Battery for Robots. Also make sure you have connected data lines properly to Arduino. So you will have to adjust the values of current limiting resistor to suit the brightness you desire.

Enable pin is used to switch between these 2 modes. I want to mount the display remote from Arduino as I need to use many inputs — will it drive say over 1 meter ok? For shorter texts more number of positions must be scrolled at a time to get a smooth display. My LCD is only displaying the first 8 characters in both the upper part as well as the lower part. Read this article before attempting the LCD version.
