I'm using this 40W adapter to power 5m of LEDs, but it seems like I could just split some of that into the 5V pin of the Arduino, correct?
I know the Arduino only wants a little bit of current,so I'm thinking it should only draw what it needs. I don't want to overwhelm it or anything.
Also, pretty technical, but I cut the ferrite inductor thing off the end of my adapter while setting up this whole LED project. I figured it wasn't a big deal. I know this might make the input current a bit more volatile, could that be a problem?
