A simple device that turns the lights on when the user approaches home.

It is a lamp or desk lamp that is controlled by your phone for when you need the light to get to your bed, but not once you are in bed.

In this tutorial we're going to learn how to use Blynk app & Arduino in order to control a lamp; the combination will be through USB serial.
