Overall plugging this shield on to Arduino will give 61 pins to work with (including existing Arduino’s I/Os), for using them as analog inputs, digital inputs, and digital outputs. Features . Adds 28 digital I/O and 16 Analog Input pins by using just 3 Arduino pins; Two Microchip MCP23017 ICs for …
Input impedance of Arduino Uno analog pins? - Electrical
/19/2011Yes, you can use the analog pins as digital pins, by numbering them 14 - 19. That's the proper way to read the pin. Well, except that the function returns a value that must be important, or you wouldn't have called the function, so toy probably want to store the returned value somewhere.
Arduino - AnalogInput
Analog Input. In this example we use a variable resistor (a potentiometer or a photoresistor), we read its value using one analog input of an Arduino or Genuino board and …

1/7/2017A description of the analog input pins on an Arduino chip (Atmega8, Atmega168, Atmega328, or Atmega1280). The Atmega controllers used for the Arduino contain an onboard 6 channel analog-to-digital
Arduino Real Time Project Ideas (Analog Input Projects)
How to Use the Arduino’s Digital I/O. June 05, 2015 by Tim Youngblood. Digital signals Unlike analog signals, which may take on any value within a range of values, digital signals have two distinct values: HIGH (1) or LOW (0). Pressing a pushbutton connected to a digital input will turn an LED on or off. The program uses both the
