Run this example from the command line with:
node eg/pin.js
var five = require("johnny-five");
var temporal = require("temporal");
var board = new five.Board();
board.on("ready", function() {
var events = [];
var strobe = new five.Pin(13);
temporal.loop(500, function(loop) {
strobe[loop.called % 2 === 0 ? "high" : "low"]();
});
// Pin emits "high" and "low" events, whether it's
// input or output.
["high", "low"].forEach(function(state) {
strobe.on(state, function() {
if (events.indexOf(state) === -1) {
console.log("Event emitted for:", state, "on", this.addr);
events.push(state);
}
});
});
var analog = new five.Pin("A0");
// Query the analog pin for its current state.
analog.query(function(state) {
console.log(state);
});
});
