This is a where a Power Mosfet comes in. With the help of the Power Mosfet, we can use the low voltage output from the Arduino ports to control high voltage/current loads -the popular “12V LED strips” ...

Smart LED strips can be remote or sound-controlled for the ultimate convenience. Simply change your outdoor light show from the comfort of your couch with the tap of a button.

Now, though, it shouldn’t be hard to control the RGB LED strips through an Arduino, a computer, or even an Android/iOS device with a small IR LED plugged into the headphone jack.
