To interact with hardware Arduino needs to take inputs and send instructions as output. To do this we have to specify an Arduino pin as an input and output. To define an Arduino pin two ways can be used: one is using the pinMode() function and the other one is defining a pin using...
/*Analog InputDemonstrates analog input by reading an analog sensor on analog pin 0 andturning on and off a light emittingdiode(LED) connected to digital pin 13.The amount of time the LED will be on and off depends on the value obtainedby analogRead().The circuit:- potentiometercenter pin ...

Per default the button pins are defined asINPUT_PULLUP. You can override this upon creation. #include"Button2.h"#defineBUTTON_PIND3 Button2 button;voidsetup() { button.begin(BUTTON_PIN); } You can also the library with other types of buttons, e.g. capacitive touch or ones handled via...
