Johnny5-uno/raspi(tm1637:raspi,lcd-i2c:uno)

https://github.com/revolunet/tm1637を改変して成功　

sudo pigpiod で失敗したらhttps://wakky.tech/pigpio-initinitialise-compile-error/で

pidを切って再度起動するのが重要　なお以下のコードはsudo node tm1637-demo.js

-------- raspiだけどvcc 5v for tm1367 --------------------------------------------------

const { Board } = require("johnny-five");

const Raspi = require('raspi-io').RaspiIO;

const tm1637 = require('tm1637');

const board = new Board({

  io: new Raspi()

});

board.on("ready", () => {

----------------------------lcd1602----------------------------

const { Board, LCD } = require("johnny-five");

const board = new Board();

board.on("ready", () => {

  const lcd = new LCD({

    controller: "PCF8574" // ここがポイント

  });

  lcd.print("Hello, Johnny-Five!");
