1 - Basic Install and Server Link
To start off with, here is how you set up your RPi for Blynk and your script for Blynk Server connection.
For Cloud Server:
const Blynk = require('blynk-library'); // Links variable 'Blynk' to the Blynk Library
const AUTH = 'xxxxxxxxxx'; // Your top secret auth code
const blynk = new Blynk.Blynk(AUTH, options = {
connector : new Blynk.TcpClient()
});
For Local Server:
const Blynk = require('blynk-library'); // Links variable 'Blynk' to the Blynk Library
const AUTH = 'xxxxxxxxxx'; // Your top secret auth code
const blynk = new Blynk.Blynk(AUTH, options = {
connector : new Blynk.TcpClient( options = { addr: "xxx.xxx.xxx.xxx", port: 8080 } ) // This takes all the info and directs the connection to you Local Server.
});
