maciejmatu / email-response.js
Created May 3, 2018 21:01
Lambda function I use for email auto-response with Netlify forms.
require("dotenv").config(); // read .env file if present.
const nodemailer = require("nodemailer");
const createHtmlMail = require("./modules/mail-template"); // this function returns html email code
exports.handler = function(event, context, callback) {
const user = process.env.MAIL_USER; // some@mail.com
const pass = process.env.MAIL_PASSWORD; // 42isthecoolestnumber
let transporter = nodemailer.createTransport({

Simplified lamp software algorithm

  1. Define constants for pins e.g. #define LED_RED 9
  2. Instantiate hueRotart, saturationRotary and bluetooth software serial
  3. Run void setup() { ... }
    1. Run startup sequence R => G => B => GB => RB => RG => RGB (helps with checking if colors are hooked up correctly
    2. Begin listening for bluetooth serial on 9600 rate
    3. Begin listening for hueRotatary and saturationRotary
    4. Setup brightness controls pins VALUE_INCREASE and VALUE_DECREASE to INPUT_PULLUP to avoid faulty readings
  4. Run void loop() { ... } in loop
