Lesson 18: Potentiometer - Elecrow Raspberry Pi & Arduino Starter Kit User Manual

LESSON 19: POTENTIOMETER
Introduction
In this example, we use a potentiometer, we read its value using one analog input of an RPI board and we change
the blink rate of the built-in LED accordingly. The resistor's analog value is read as a voltage because this is how the
analog inputs work.
For this lesson as the previous lessons we'll use the PCF8591 module in order to read the values from the
potentiometer.
