Arduino Circuit to Dim LED with Potentiometer

In Lesson 8 you learned to write analog voltages on the Arduiono, and in Lesson 10 you learned to read analog voltages from the arduino. In this lesson we will combine what you did in lessons 8, 9, and 10 to create an LED with adjustable brightness. The brightness will be set based on the position of the potentiometer. In order to do this, we need to set the potentiometer up as a voltage divider, and we nee ...
