您好，有人可以帮助我解决这个简单的问题吗？

我有一个传感器连接到 arduino巨型板，并且正在使用 UART 协议。 在 johnny-five.io 上，我没有找到有关 UART 协议以及如何连接Tx1和Rx1引脚的示例。

这是我的草图

'''

const five = require('johnny-five');
const Oled = require('oled-js');

const board = new five.Board();

board.on("ready",function() {
    const sensor = new five.Sensor(18);
    sensor.on("change",value => {
        console.log("sensor");
    });
});

'''

当我使用node运行js文件时，出现以下错误。

    TypeError: Cannot set property 'report' of undefined
