First of all I’m sorry if I posted this in the wrong place/thread/topic/section and Yes, I made a lot of research but I’m so n00b that I have to ask someone to give me a little help.
Here is my situation: I have a 24v/1A (that’s a lot of watt!!) that’s used for light a powerful LED.
What I want is to know with an arduino due what LED are ON and what are not.
Obviously I need something that drops the current from 24v to 3.3v, but I also must be sure that arduino do not get too many amps.
Or did I just say a truck of bullshit?
Just to explain a little better:
24v source > ------ < 24v user
the code doesn’t scares me, it’s simple, but I’m a complete idiot in electronics.
Could some good greg guy give me a help?
Thanks in advance for anything!
And sorry for my english, is so outdated!
