# Pin

Run with:
```bash
node eg/pin.js
```


```javascript
var five = require("johnny-five"),
    temporal = require("temporal");

(new five.Board()).on("ready", function() {
  var events, strobe;

  events = [];
  strobe = new five.Pin({
    addr: 13
  });

  temporal.loop(500, function( loop ) {
    strobe[ loop.called % 2 === 0 ? "high" : "low" ]();
  });


  // Event tests
  [ "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 );
      }
    });
  });
});
