Hi, Im looking to build a simple arduino circuit whereby a motion sensor turns a strip of LED lights on (one colour LED strip).
i have been able to successfully do it with a single LED light with and without a bread board and resistor, but when I tried to hook it up to and LED strip it simply didn't light up.
I then eliminated the motion sensing part of the circuit and again was able to light up a single LED but it doesn't light up the strip.
I have connected it via the barrel port to the wall wart and I'm using Arduino UNO R3.
Can anyone tell me what I need to do to get the LED strip to work with the arduino board. I'm using the gnd pin and pin 12 and its working fine to power a single LED, but what about a strip? Do I need a relay or a transistor?
Perhaps someone could draw up a circuit I could copy?
