My next challenge is to figure out how to make sure our node script is running on boot of the raspberry pi.
This is our simplified script we want to run at system boot.
var wpi = require('wiring-pi'); var express = require('express'); var app = express(); wpi.wiringPiSetup(); var relaySwitchOne = 0; wpi. . . .

Relay tied into an extension cord, C_LOG_23
Now that I have the relay hooked up I was able to make the small LEDs on the relay flash it is now time to use it to switch power. Before we get started I would like to state I really don't know what I am doing but do have some basic electrical experience and need to state we are now dealing with 120v which is dangerous. Please be careful . . .
A couple weeks ago I purchased a SunFounder 2channel 5v relay so I can use the Pi to control a device remotely (I am looking at you Mr. Christmas Tree)
This was the first time pulling it out of the box and immediately I was confused on how to hook this thing up as there were no diagrams or instructions. After much googling, reading . . .
