Topic: Voltage fluctuating too much. How to fix? (Read 9506 times) previous topic - next topic


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?


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?
