I am beginner enthusiast. I was trying to make lights under my bed by following this tutorial:
It worked for me with a 1 meter color RGB led strip. However, when I put a white LED 5 meter strip, it can not go bright enough and it seems to be at 30% brightness.
The only MOSFET I have at home is IRF520. Is this the reason for my dim light? If yes, what kind of MOSFET would fit? Is there a way I can learn to calculate it?
