I was thinking that maybe I should make a separate power line for the buzzer and the LCD backlight as they are drawing too much current? Or maybe put the two sensors on their own 5V regulator and all the rest on a separate 5V regulator?

Please factor this in

Would that solve the problem? What about the ground lines, does it matter if I power the sensors from a separate 5V regulator but ground them to the Arduino's pin?
