Usage

// Invoke this method to set the pull mode. pullType can be - pullup, pulldown or none.
pin.pull(pullType, callback);

Example of the pin.pull(mode) command using a pushbutton. The code example given below turns on the Blue LED of the Tessel module when the pushbutton is pressed and turns off the Blue LED when the pushbutton is released.

var tessel= require('tessel'); // Import Tessel

var pin = tessel.port.A.pin[2]; // Select pin 2 on port A

var pullType = "pullup"; // Set the mode of `pin.pull to pullup`

var led = tessel.led[3]; // Blue LED of Tessel

pin.pull(pullType,(error, buffer) => { // Pin 2 pulled high

  if (error){
    throw error;
  }
});

setInterval({
  pin.read(function(error, number){

      if (error) {
        throw error;
      }

      // Pin 2 reads high when the pushbutton is not pressed since it is pulled up
      console.log(number);
      if (number == 1){
        led.off();
      }

      // Pin 2 reads low when the pushbutton is pressed since its connection with ground gets complete
      else{
        led.on();
      }

  });

}, 500);
