Running script forever with foreverjs

Reboot! C_LOG_26

My next challenge is to figure out how to make sure our node script is running on boot of the raspberry pi.

Simplified Script
This is our simplified script we want to run at system boot.

var wpi = require('wiring-pi');

var express = require('express');
var app = express();

Controlling the Flow

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 . . .

Pump up the Pi

Migrating to a larger microSd Card, C_LOG_15

In my pi adventures I think it is time to swap out to a larger microSd card. I was able to pick up a class 10 32gb microSd card for about $12 dollars.

Trying out Wiring Pi

Write to that GPIO real good, C_LOG_12

Previously I tried out the pi-gpio package to get my led to flash, but wanted to explore other options. After a bit of searching around the internets I stumbled upon wiringPi and a corresponding node wrapper.

The documentation didn't have any apparent quick start examples but after reading a few examples. I clobbered together an . . .
