This Raspberry Pi, IoT Doorbell is basically a simple smart Door Bell, which takes a photo of whoever rings it, and emails it to the specified email address, and keeps all the photos in a folder. (along with going Ding-Dong). This is my first Instructable so I hope you enjoy :)

How I have set out setting this up is: OLD:

the camera is looking at the door bell. I couldn't have the camera above the box because my lead is not long enough

If you wish to use the pi camera instead of a webcam:

nodes19chamb and MichaelM1252 have commented some code that should help! Thx guys.

-----UPDATE!!----

I have Got a new setup where the Button Cable is routed through a small gap in a window next the frount door where the camera taped so it is looking out the window,

PS: The camera quality in my examples is bad because I have a bad camera.

Step 1: Parts/ Tools

Here is the list of parts with approximate prices and links, though you don't need to buy these exact parts

NOTE: :Project costs around $110, Though price can be made cheaper/ more expensive depending where you buy the parts, or using an RPi 1/2.

ALL PRICES ARE IN AUD,

Raspberry pi $55, I've linked Raspberry pi 3, though any should work, though you will need a Wifi adapter if you wish this project to be wireless. You can also use the Raspberry pi 1 B and save $20

Wi-Fi Adapter $10You don't need this if you're using ethernet or RPi 3.

Pi Case $14You don't need this but i recommend it so your pi doesn't get damaged.

Mini Breadboard $1.29 to do wiring on

Button $1.29 (waterproof, Normally Open)

Lengthy wire, to from pi to doorbell

1K resistor, $2.48required for button circuit (only one needed)

Bread Board Jumper Cables $5.19 - you only need 3 :)

Webcam $4 - $100

Box to hold button in $2-10

_____________

Tools:

Soldering Iron (Recommended)

Wire Stripers

Side Cutters/Sharp scissors

Computer

Internet

Step 2: Setting Up Hardware.

-------------------

IMPORTANT:

I made some mistakes:

It is 5v not 3v

It is 10K Resistor not 1K

------------

If you are using a non B+ Model

you will have to use GPIO 7 (or other) instead of 21!

-------------------

Hardware is pretty simple. Plug your Webcam into the Rasp-pi, along with your selected network interface. Then, using the images as a guide (the wiring diagrams + this pinout for rasp pi 1B), connect your button and resistors to the pi. With the breadboard image, the orange and blue wires are the wires running the the door bell (Project Box with button).

Step 3: Making the Door Bell

To Make the door Bell you will need to cut a 12mm (1/2") hole in the centre of the project box, and around a hole near the bottom for your wires. Im my case I have taped over the bottom hole(and wires) to stop water from coming in.

Step 4: Software & Programing

Now This is the harder part. First off SSH into your Pi (Raspbian Wheezy or Later).

--- Wondering how to SSH?

here you can find instructions by Antares72 for setting up SSH on Windows with the Pi

Or see here for instructions for Linux or Mac users.

________________________________________

For the "Advanced Users, I have put comments in the code explaining how it works

Follow these instructions (Once in the command line) (copy exactly

Remember to NOT copy the " $ " in these commands if you are copy and pasting.

First, make sure your in your home directory (or whatever directory you wish to install the program to ( PS: it is contained in one folder, so it won't go everywhere in your home directory)

$ cd ~

Then we want to download the dbell folder containing all the code:

$ git clone https://github.com/Happypig123123/dbell.git

Now we want to CD into the directory

$ cd dbell

$ mkdir photos

-------VERY IMPORTANT!!!!!! -------

# NOTE: If you do not use B+ Model, you will need to change the "Button" variable in bell.py from 21 to a # pin number that's available on your pi. TO do this do

# $ nano bell.py

# and change the Button = 21 line to something like Button = 7

# Pinouts are on the "Setting Up Hardware" Setting Up page

Now our setup is time to start editing the email code.

Step 5: Gmail Setup

Gmail?

To be able to send an email with a photo, the raspberry pi needs its own email account. For this we use GMAIL. So click here to sign up for a Gmail account. You can use one you have already created, but you will not be able to receive the notification, that someone is at your door, with it. Also, we will be disabling some security features, making your account more vulnerable to hackers. Step 1a: To Google, the raspberry pi is an "Insecure" Device, so we need to let Google let unsecured devices, (i believe this means devices not using https) login. To do this we:

1. Follow this link (opens in new tab), and log in with your "raspberry pi's" Gmail account you just created.

2. Scroll down to the bottom of the page and you'll see an "Allow login from less secure apps" card. Click the switch to change it to yes. (image of no state above)

Step 6: 3.5.6) Email Script Customisation

Ok Now we setup the Gmail account we can now set up the Email Script. I would like to give credit to Gagandeep Singh, for his code is used in the IoTNotify script, And Sentdex, for his tutorial on python email tutorial, which allowed me to understand the process.

For the more advanced users who want to know how this works, Check out Sentdex's tutorial as I have not explained at all how this script works.

Now do this:

$ nano IOTNOTIFY2.py

and change the following values:

Do this for all of the Fields

to the Gmail account email address E.g: exampleIoT@gmail.com

Yeah, Ass-Word, Wops, Spelling Mistake...

to the email you want to be notified at (eg: your personal email that on your phone, so your phone goes "Buzz" When someone's at the door)

After you have changed all the values, press Ctr X, then Y to save the document
