12 Lesson 8: Knob control brightness 

12.1 Overview 

The  knob  angle  can  tell  you  the  angle between 0  with  280  degrees.  It  is  usually  used  to control 

brightness of display, volume of speaker, voltage of power and speed of motors. 

In this lesson, you can learn to use the knob(rotary angle sensor) to control the brightness of the 

display.
