Power Supply or Resistor Solution?
Morning everyone! I have a small question I want to operate 2 strips like this one with an Arduino Mega, the LEDs look a bit dim when I turn them on, like a drop in power! Should I power them with another 5 volts or should I add resistors? If resistors, how many ohms? Thank u in advance.
Solution
Adding resistors won't help, they'd just make the LEDs dimmer. a relay can be used to control power to the LED strips, maybe you need a additional power supply The issue might also lie with the LED strips themselves...
