The purpose of calling the pinMode() function on a digital pin before using it is to set the pin to behave either as an input or an output. This is a necessary step in Arduino programming.

Here are the steps:

1. The pinMode() function is called in the setup() function in your Arduino code. The setup() function runs once when you press reset or power the board.

2. The pinMode() function takes two arguments, pin and mode. The pin is the number of the pin you want to set and the mode can be either INPUT or OUTPUT.

3. If you set the pin as INPUT, you are setting it up to receive data, like from a sensor. If you set it as OUTPUT, you are setting it up to send data, like to a light or motor.

4. Once you've set the pin mode, you can use the digitalRead() function to read the state of an INPUT pin, or the digitalWrite() function to set the state of an OUTPUT pin.

In summary, the pinMode() function is used to specify the role of a digital pin in your Arduino project.
