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.
Before we begin we'll need graph paper and a straight edge
slope = the change in y divided by the change in x
m = yf - yi / xf - xi or y final minus y initial divided by x final minus x initial
(yf - yi) = m (xf - xi)
Please gather the material required and follow along with Mr. McWhorter
