Arduino LESSON 10: Analog Reads on the Arduino
In today's session, we'll learn how to read voltage readings from a basic potentiometer circuit using the analogue pins on the Arduino. The anolog pins are the A0 to A5 pins of the Arduino Uno. These are the pins that may be used to measure Analog Voltage.
Today's circuit is a basic voltage divider based on a potentiometer. Lesson 9 describes the operation of the potentiometer.
This simple circuit allows you to create a voltage divider with a potentiometer
