Run this example from the command line with:
node eg/grove-servo.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 Servo module
// into the Grove Shield's D5 jack
var servo = new five.Servo(5);
// Set scaling of the Rotary angle
// sensor's output to 0-180° (8-bit)
// range. Set the servo angle in
// degrees corresponding to the
// value of the sensor
rotary.scale(0, 180).on("change", function() {
servo.to(this.value);
});
});
