How do I know whether or I am using the pin as a digital or analog input? Even though I call it A0, maybe I want the pin to be digital. Additionally using the designator A0 instead of 14, on an Uno, I know I mean the Analog pin. So if I look at setup() and see I am pinMode() on the pins, I’ll know I’m using it. Why use pinMode on Analog Inputs?īecause when I look at the code, especially after a long break, I want to know what pins I am using and how. Keep reading to see why I use pinMode on Analog Inputs.
However, when I write Arduino Sketches, I still put a pinMode(A0, INPUT) in setup anyway. For this reason, it isn’t necessary to call the pinMode function on the pin.
For example, when calling analogRead(), an analog input pin is automatically changed from a digital input (or output) into an analog input. The Arduino functions have different calls depending on the pin type. All Arduino boards contain analog and digital pins.
