Controller LED with Potentiometer

Controller LED with Potentiometer:

For this lesson we had to control the LED to make it turn on and off, by using an electric dial, controlling the electricity. letting you turn the LED, on and off, when ever you want, with a couple of other attachments, to the breadboard. Such as one LED, any color, one resistor, blue, or brown, the blue resistor, work best for us. then added a black wire to the Ardunio board, then add another black wire which will be the ground wire, near LED, and resistor. then we connected a red and white wire, to the bread board, and Arduino board.
