Driving and LED strip from an Arduino with a transistor.

This video is a simple demo using a transistor to drive an LED light strip with an Arduino.  Since an Arduino only outputs 5 volt on it’s pins, but and LED strip requires 12 volts.  To do this I used a transistor to run a second voltage source to supply the 12 volts to the LED strip.NOTE:  The transistor used was an NPN type.I’m not completely happy with this video, but I was pressed for time.
