Fritzing diagram: multi-SI7021.fzz


Run this example from the command line with:

node eg/temperature-SI7021.js
const { Board, Thermometer } = require("johnny-five");
const Tessel = require("tessel-io");

const board = new Board({
  io: new Tessel()

board.on("ready", () => {
  const thermometer = new Thermometer({
    controller: "SI7021",
    port: "A"

  thermometer.on("change", () => {
    const {celsius, fahrenheit, kelvin} = thermometer;
    console.log("  celsius      : ", celsius);
    console.log("  fahrenheit   : ", fahrenheit);
    console.log("  kelvin       : ", kelvin);
