in today’s lesson we will learn how to use the analog pins on the arduino to read voltage values from a simple potentiometer circuit. The anolog pins are the pins marked A0 to A5 on the Arduino Uno. These are the pins that can be used for making Analog Voltage measurements.
The circuit we will be using today is a simple voltage divider using a potentiometer. Lesson 9 gives a description of how the potentiometer works.
