Control led strip light with arduino from 12v? Answered
Hello, I would like to control my 12 volt strip light (not RGB) with an arduino and also use a potentiometer to be able to adjust the brightness manually.
However I am afraid to fry my arduino board with 12v directly as it will fry it and I also want to be able to use higher voltages in the future but for the time being only 12v volt will do.
I don't really know what to use to control high voltages and current so as to be able to control it. My choices are relays but most are from 220v to 12v and can only be on and off so very difficult to control brightness.
Another choice would be to use my potentiometer but again I don't know how to control it and especially about the value such as 10k for example.
Then there is the use of transistor such as MPN and NPN which I don't remember how to use.
It has been at least 4 years since I was in electronics and now want to get back in so as to create awesome things but I need to be sure that I am safe and for other people as well.
Thanks again for you help.
