How to Make a Smartphone Connected Door Lock

7 років тому

See how we built it, including our materials, code, and supplemental instructions, on Hackster.io: www.hackster.io/hackershack/s...
In this video, we show you how to make a smartphone-controlled, internet-connected deadbolt actuator powered by a Raspberry Pi that can be added onto your existing door lock without any modifications to the door. The door lock can be controlled by multiple smartphones, and even notify you whenever someone locks/unlocks the door. All of this is done using a simple, drag-and-drop app builder (www.blynk.cc/) which makes building your own Internet of Things (IoT) app easier than ever. For an extra impressive door lock, we'll also show you how to add a simple LED light to indicate if the door is locked, and a push-button to operate the lock manually.

Guys, I just stumbled onto your site today. You two rock! This is a GREAT site. I am pretty obsessed with home automation and seeing what home users can accomplish. I love that you guys are giving us great tools and the projects are in stable shape. Seriously making them pretty and hiding wires and painting cables.. I would rather we do that and you guys concentrate on the bones and muscle of the projects. (I am just putting that in cause amazed when people are complaining about "I see wires!!!!". They should know how to hide a wire!) I am looking back now at your project list for fun cool ideas! you ROCK!

@pepijndemeer554 7 років тому

You guys deserve way more subscribers! Also keep up the good explanation of what to do. It's really helpfull

@thatsblackout5472 7 років тому

EXACTLY WHAT I WAS SEARCHING FOR LOVE YOU

@TheSanderAble 7 років тому

Really like the lock you made. I made a similar project. it's the same principle but I added a raspberry pi camera with opencv so that it automatically warns you when there is someone at the door.

@TheSmartHomeHelper 4 роки тому

@heimdallmidgard4670 6 років тому

Little overkill with a Pi. ESP8266 with sleep mode and 18650 would be nice so you don't need a charger all the time.

@smoresrock 4 роки тому

came here to say this. you could probably get away with using an arduino and the smartthings library for example

@steviewonder5895 2 роки тому

This is so cool! Thank you for sharing. I have a question; Can you use your key still to unlock or it wont let it turn?

@nickstefanisko 5 років тому

Any thoughts on using an HTTP server on NodeMCU rather than a NodeJS on Pi. I'm thinking less complexity, less spaghetti. A magnetic closure sensor would be cool too so that you could also open/close state.

@finndriver1063 7 років тому

could you have a small onboard battery that could power the pi for a few minutes and then some contacts on the top of the door to transmit power when closed? that way wires could be routed in different directions.

@sam19r 4 роки тому

Great tutorial, what if i want to lock/unlock by my own mobile application?

@danielpierce922 4 роки тому

Kits? can you give an SD card with all the tec parts done? So i can just plug and play with my Pie? Anyways, awesome vid! I'm doing to a door that's a secret door to a secret room. It'll also be spring loaded so it'll unlock and open. I'm going to put most of this inside the door and connect the wiring inside the wall. Been wondering how to do the lock on this door, so thanks again!

Antonio Fontes totally agree with you, I love this channel but the 3-4 weeks before a new video does kinda drag. But I do understand the wait.

@BankruptGreek 5 років тому

For doors with not a turning handle on the outside, would it be possible to remove the door knob lock (we call it tongue in my country, I am talking about the thing that closes and opens when you turn the door knob). Remove it or replace it with one that opens and closes with some basic force then have an external lock that has a female insert screwed on the door and a male remote controled piece on the wall that locks the door tightly closed using the app. that way you can still use your doors lock system and as a backup and keep that unlocked when you want to remotely open the door by opening the external mechanism.

@kendirwayi 7 років тому

wow!! this video is awesome and the presenters are just on point. thank you its really enlightening. i am wondering though, if i want to use Arduino-Uno instead of Raspberry Pi and use Sim800 GSM module for accessing my micro-controller instead of blue-tooth module do i need to have an external power supply for the servo or Arduino power supply still works?

@roasthunter 7 років тому

Probably works in America that use that type of lock. Here in the UK the locks are generally integrated on the door handle and dont have manual overrides, but an interesting project none the less.

@chylerlzer4029 4 роки тому

this is awesome video!but can we use arduino uno r3 instead using raspberry pie?

@diegovknight69 7 років тому

@iansss5076 6 років тому

Hi what if instead of using servo motor I'll be using a solenoid, would it affect the setup and the output?

@rooster443 5 років тому

Just use esp886 and some microcontroller like stm32 still there's a need for a server or computer logged into internet so we can access and that's why we use raspberry. Miss you guys, hopefully you are doing great in your other projects. UKposts isn't enough anymore

@novechotango5033 6 років тому

Good day, Is it possible to merge or connect two of your projects: Smart Security Camera and Smartphone Connected Home Door Lock in one project? Does the raspberry pi 3 can run them simultaneously? Thank you

@somairm 6 років тому

Really excellent Video. It would be nice if you add google home or Amazon Alexa to lock the door as well.

@squesh1261 4 роки тому

Is blynk compatible with the pi 4? If it is, what option in the blynk app do I choose? I'd really appreciate it if u guys could respond. I need it for a school project 😅

@elielepetit8107 2 роки тому

waaaaaaaaaaoooooooooooh:!!!!!!exceptionnal project

@Sculas 5 років тому

This looks really nice, but also really dangerous if someone really uses this. Blynk has to get 1 database breach and every door can be unlocked by logging in and yeah, opening the door. It looks fun for other things tho! :)

@himstien 2 роки тому

Can you still use the existing physical key to unlock the door while also using this automation? Wouldn't the servo be stuck at its the last state ?

@LAStupidDrivers 7 років тому

Thanks for share you work. How blink apps know if the door is locked or unlocked? The app read the status of the led for see if is locked or unlocked?

@cmiller1515 7 років тому

What if you made the lock voice activated? Perhaps similar to the smart mirror, except it locks, and unlocks the door.

@hackershack 7 років тому

+bootlegged_cake great idea. Maybe we'll make an update video about it :D

@saikrishnaseethala3994 7 років тому

Can't we make it much cleaner than that? I mean all in one piece.

@jahwni 7 років тому

So the thief can come up and say "unlock"? lol

@cmiller1515 7 років тому

lankyfingers If the lock was activated by a voice controlled script, it would most likely be behind a sound proof door, with the mic facing inside the house, and not outside. If you wanted a voice unlock outside, you could even program it to only unlock when a certain voice is heard.

@jahwni 7 років тому

Yeah I know, was just being silly =) would be cool to have it so you could speak to your phone to unlock it, rather than having to yell across the room to the mic facing you etc.

@AztecWarrior69 4 місяці тому

Yeah this is nice, good work by the way, but there are door jam bolt release mechanisms that you don't have to make any 3d printed stuff. They don't cost much either. You can have the wire hidden behind the trim boards. And by using an MHCOZY smart switch you don't have to do ANY arduino programming. You can even use the Bluetooth function on the MHCOZY to open the door when your phone is close to the door.

@AztecWarrior69 4 місяці тому

You can also have gaagle's always listening function to unlock the door when you say "Hay gaagle unlock my front door.". For those times you're holding a bunch of groceries.

@AztecWarrior69 4 місяці тому

@TheBadFred 7 років тому

should be a nodeMCU or ESP8266 enough, instead of a relatively expensive raspberry pi 3 ?

@falias4 7 років тому

TheBadFred the RasperryPi is definitly an overkill, when it's just about WiFi and some IO-Pins. Blynk also supports ESP8266 according to their website.

@yanir.tzabary 7 років тому

SO juse need to use same GPIO HEADER?

@falias4 7 років тому

Yanir just google it.. there are enough tutorials and howtos on the internet ;)

@yanir.tzabary 7 років тому

but i want to use this project, as i undestand just need to use same GPIO HEADER on Raspberry pi Zero :)

@sailingdev 6 років тому

Got it working with the NodeMCU, it gets super hot after a while tho. I'm powering it with a phone external battery

@SparkableGlow 6 років тому

Could you add another button on the case that is programmed to lock or unlock the door depending on which state it is in? I don't know too much about this kind of stuff but for sure want to learn about it. The servo is it always in one place until told to be moved or can it be freely turned as you want but moves when it is told to? If it can be moved freely an opening could be made on the casing so you could reach a finger in a turn the lock physically right? Also, does the servo keep track of how much it has turned or is it just a motor that moves when it is told? I would love to learn about this so if you have any knowledge to share please do so! Thanks.

@vikrammishra7601 6 років тому

For the button part, you can just add an if statement in the code

@vincejohn8370 7 років тому

where do I buy the kit? my grandma need this she always forgets her keys and always call me and I live on the other side of the town.

@-.......................- 4 роки тому

@MEME_PLAN Рік тому

Does the lock work manually too if the device is set on the door?

@nelsonc5339 6 років тому

Good _overview_ of building a door lock. So _many_ security issues/worst-practices (holes) though... 😧 Next video in this series will be: "how our house got hacked"! If you end up selling kits, make sure you include a disclaimer!

@qwarlockz8017 6 років тому

This would be great though for in inside door lock. If you have room mates and want a lock on your bedroom or you have one room that is your work area that you want the kids to not get into.

@beroichoberoichev9501 7 років тому

Question - What would you do if there is no power and the electricity is cut? Can you add backup battery power just in that case and this battery to be used only when the primary electricity circuit is not working. And if that is possible how woul you do it(connect it)? :)

@johndonut2426 5 років тому

Thanks. But why would you not combine a 3d printed housing for the Pi as well so it doesn't look like garbage.

@cwbh10 5 років тому

@thelatinbrother6596 6 років тому

hhaahah que buen proyecto yo estaba intentando hacer algo así pero con jarvis.

@calendil 4 роки тому

A couple of suggestions to improve your project: couple the servo with a gear and put a thru shaft. Gear should engage to the shaft on shaft's axial movement (like a car gear box). Put a handle to the back end of the shaft and a spring which would push the shaft towards gear. When someone pushes the handle from inside that would disengage the gear, and you can lock/unlock the door manually by the handle. I hope this makes sense.

@martinmchugh1924 6 років тому

Great project. The only thing I'd say is that, to get the same functionality with an ESP8266 would be infinitely simpler and cheaper. Still, if it's a Raspberry Pi project you're after, this is a great one!

@TwanJaarsveld1 Рік тому

and it will run Esphome and it could be used in Home Assistant

@glen4cindy 7 місяців тому

I'm seeing this several years after it was made and I'm trying to think of how it could be miniaturized even further. If you used an ESP8266 you could put a battery on board to run the ESP and then you wouldn't have wires running from the Pi to a power source.
