In this Instructable, I will detail how I made my own homebrew home security system based on Arduino. I will admit, it's not the most secure in it's current state, but given certain modifications and higher grade components along with tweaking of the code, it could prove to be a formidable system.
There are many different aspects to the Arduino program that you will most assuredly learn along the way, such as switches, debouncing, LCD displays, and a few more. This guide will show you how I myself went about the process (and I am always open to comments, questions, and criticism!).
Step 1: Requisites
First of all, I will assume one has a basic to intermediate level of understanding of the following -
-Arduino - writing sketches, using the IDE, etc.
-Some basic soldering skills (I'll admit, I am surely not the best!)
-For this particular Instructable, you will need (or might need) -
-16x2 LCD Display
-Magnetic Reed Switch (also a magnet)
-PIR Motion Sensor
-DS1307 Real Time Clock
-3V Coin Cell Battery
-5v Regulator (LM7805)
-10uF Electrolytic Capacitor x2
-10k Resistor x3
-LED (I used a superbright white LED)
-Iron Ferrite Choke
-A generous length of CAT5 cable
-A breadboard or two.
-Solder (of course)
-a bunch of jumper wire (the more the merrier!)
-any spare female wiring you can get your hands on. I have a bunch of computer parts, so for me, this is in no short supply!
(Please forgive the messyness of my parts bin! :P)
