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.

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...

If you're powering them with arduino's 5v it won't be enough ypu could use boost converter like this to power the leds and use arduino pins only for control the relai board but don't forget the common GND
I think this is an extra step as she already have a relay...
I meant to power leds 😅NVM
