Sensor - Photoresistor

Breadboard for "Sensor - Photoresistor"

docs/breadboard/photoresistor.png

Fritzing diagram: docs/breadboard/photoresistor.fzz

 

Run this example from the command line with:

node eg/photoresistor.js
var five = require("johnny-five"),
  board, photoresistor;

board = new five.Board();

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

  // Create a new `photoresistor` hardware instance.
  photoresistor = 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: photoresistor
  });

  // "data" get the current reading from the photoresistor
  photoresistor.on("data", function() {
    console.log(this.value);
  });
});
