Run this example from the command line with:
node eg/grove-rotary-potentiometer.js
var five = require("johnny-five");
var board = new five.Board();
board.on("ready", function() {
// Plug the Rotary Angle sensor module
// into the Grove Shield's A0 jack
var rotary = new five.Sensor("A0");
// Plug the LED module into the
// Grove Shield's D6 jack. See
// grove-led for more information.
var led = new five.Led(6);
// Set scaling of the Rotary angle
// sensor's output to 0-255 (8-bit)
// range. Set the LED's brightness
// based on the value of the sensor.
rotary.scale(0, 255).on("change", function() {
led.brightness(this.value);
});
});
