Run this example from the command line with:
node eg/potentiometer.js
var five = require("johnny-five"),
board, potentiometer;
board = new five.Board();
board.on("ready", function() {
// Create a new `potentiometer` hardware instance.
potentiometer = new five.Sensor({
pin: "A2",
freq: 250
});
// Inject the `sensor` hardware into
// the Repl instance's context;
// allows direct command line access
board.repl.inject({
pot: potentiometer
});
// "data" get the current reading from the potentiometer
potentiometer.on("data", function() {
console.log(this.value, this.raw);
});
