Variable Resistors

  • David Cook


The brightness sensors and balancing dial at the front of Sandwich are variable resistors. In this chapter, you’ll learn about variable resistors and you’ll prototype the first portion of the line-following circuit. Along the way, you’ll run across techniques for simplifying schematics.
