var five = require("johnny-five");
var board = new five.Board();

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

  var lcd = new five.LCD({
    // LCD pin name  RS  EN  DB4 DB5 DB6 DB7
    pins: [7, 8, 9, 10, 11, 12],
  });

  var frame = 1;
  var frames = [":runninga:", ":runningb:"];
  var row = 0;
  var col = 0;

  // These calls will store the "runninga" and "runningb"

  lcd.useChar("runninga");

  this.loop(300, function() {
    lcd.clear().cursor(row, col).print(
      frames[frame ^= 1]
    );

    if (++col === lcd.cols) {
      col = 0;
      if (++row === lcd.rows) {
        row = 0;
      }
    }
  });
