WebThe digitalRead () function is used to read the logic state at a pin. It is capable to tell wether the voltage at this pin is high (~ 5V) or low (~ 0V) or, in other words, if the pin is at logic state 1 or 0 (or HIGH/LOW). Notice that the digitalRead () function does not effectively measures the voltage at the pin.
