Sorry if this topic is already discussed, I couldn’t find anything.
(Also I am very new to the arduino world. )
I am trying to control an LED light panel. For the most part the controls seem to be working, however I am not able fully turn the panel off. It goes from about 10% to 100%. I was mostly trying PWM to have a very slow dim but it never fully went off. Also tried just having the panel turn on and off every couple seconds to make sure, still no.
AC/DC adaptor from the wall ~ 12V, 2A output
connected to my bread board
using a Mosfet transistors [IRF520] to split the ground
The panel secs are:
input : 12v dc, .67A,
I attached a photo of the arduino setup, and a video of the panel (the auto exposure is affecting the brightness, however you should be able to get the idea)
I am thinking it is likely the MOSFET being improperly sized, but am not sure where to look to get that information, or how to properly read it.
The end goal for the project will hopefully be painting on the panel and having an illuminated painting, possibly which changes lighting with the time of day. Or at least this is my starting idea.
Any help appreciated.
