Grab your motor and board, and follow the diagram in the previous section to wire a motor. Let's use pin 6 for the signal pin, as shown in the preceding diagram.

What we're going to do in our code is create a Motor object and inject it into the REPL, so we can play around with it in the command line. Create a motor.js file and put in the following code:

var five = require('johnny-five');

var board = new five.Board();

board.on('ready', function(){

  var motor = new five.Motor({
    pin: 6
  });

  this.repl.inject({
    motor: motor
  });
});

Then, plug in your board and use the motor.js node to start the program.

> motor.start(125);
