You have actually learned quite a bit in the first 13 lessons, and now we are ready to bring it all together in an interesting project. In this lesson, we will show you how to build a dimmable LED. You will read values from a potentiometer, and then based on what value you read, you will set the brightness of the LED. This is a really cool little project, and will no doubt get you thinking about bigger and better things. If you want to follow along at home, you can order the Arduino Kit we are using HERE.
