running LED strip on ac Answered
So i started working on a new project with RGB LED strips and I needed a power source, I dug around my box full of wall warts and saw one that said 12v 3000mA and thought ''perfect!''.
I never hit the wires with my multimeter, just used a spare chunk of led strip to figure out polarity.. Anyway, plugged a line into my strip and into my LM7805 and blew my voltage regulator, only then did I look at the power supply and notice it was 12v AC!
So to my question (sorry for the long winded intro) How are my LEDs working with AC power?? I switched the leads and they turn on with either line attached, so its obviously alternating, but how could these turn on at all?
