Hello, I have used a spark core to control some 12v LED strips using a simple setup tutorial from adafruit. This works well but I am powering the spark with the USB charger and the LED’s with a 12v wall wart (shared ground). I Would like to simplify so that I only need one power supply. Looking for an easy way to do this (suggestions?) I found this and was wondering if it would work.
Is it this simple?
BTW, here is the adafruit tutorial/setup I am using.
