Configures the specified pin to behave either as an input or an output. See the description of digital pins for details.
pinMode(pin, mode)
pin: the number of the pin whose mode you wish to set
mode: either INPUT or OUTPUT or INPUT_PULLUP
None
int ledPin = 14; // LED connected to digital pin 14
void setup()
{
pinMode(ledPin, OUTPUT); // sets the digital pin as output
}
void loop()
{
digitalWrite(ledPin, HIGH); // sets the LED on
delay(1000); // waits for a second
digitalWrite(ledPin, LOW); // sets the LED off
delay(1000); // waits for a second
}
The analog input pins can be used as digital pins, referred to as A0, A1, etc.
