3D Printed RFID Door Lock - Using Arduino Uno and 5V Stepper motor (free .stl files and code)

3D printing and Arduino is just a perfect match, this is the first video on this channel using Arduino. Where I got the idea to make a door lock? - Well the RFID module is just soo cool and I wanted to use that and where is better to use this then door lock? I have seen on KZbin also where people had build door lock with RFID module using servo motor, but never seen with stepper motor, soo I give it a try. I am planning to make a project where I use Arduino a lot more.

Happy face when you came back after a long weekend and... batteries are expired! ...

[@NextElonMusk]

hahahah

[@OlafurJonBjornsson]

one improvement that comes to mind, mirror the whole thing, keep the mechanishm on the wall, hide the box somewhere, and plug it in

[@Shadow__X]

And put an emergency method like a code combination lock somewhere hidden on the outside

[@abhishekbhanderi6013]

Hey! Its a good explanation. Crisp and precise ,well done

[@togitegan9889]

I have a suggestion for future projects where a mechanical switch is required to determine a binary position of a sliding part. Instead of using a push button which requires somewhat precise positioning, use a microswitch with lever, which can be pressed up by the rod sliding along it.

[@justkalola6604]

woooooooo great going my friend

[@fswarrior9510]

Good video and good explanation, keep it up bro

[@Eden_M]

1:40 this old tony style cut, loved it haha 👌

[@lelandclayton5462]

A few things. Could use a ESP8266 such as the D1 Mini so it makes the overall size smaller. Could of taken a Barn Door Lock and modified it with 3D printed parts to add the Stepper portion. Ditch RFID and use MQTT so all you need is a App to control it and no need for anything on the exterior part of the Door.

[@aeroworxsg7597]

what to do when phone battery is flat and the charger inside? ( maybe just kick the door and the plastic lock breaks hehe )

[@SebTard]

I'm making the same thing but with magnets and a printed circuit, it's a little bit more expensive to do a personalized printed circuit but it's better than the cable jungle, still the 3D printed stuff looks really good

[@alice20001]

God that opening with the sharpie noises just kill me

[@julianreichwein5790]

Apart from the mechanical weakness, you could open the door by cutting the wires going to the RFID Module and just send a "granted" signal or connect your own RFID reader. Why not put the reader behind the glass? It would probably still work

[@TNoStone]

As if somebody is going to do all that

[@paulz1780]

I know I'm a bit late, but these RFID Readers transmit the raw data of the key. The Access Handling is done in the Microcontroller

[@julianreichwein5790]

@@paulz1780 Ah okay, thanks for the information. That makes a difference

[@UnwrappingByMimiKoteng]

Amazing

[@sameheid2446]

Very good. I wish you great success .. but there must be a magnetic sensor for the door that sends a shutdown signal to the motor.

[@IndrekL]

Hey! You are showing the wrong version of your Arduino code in the video :) There is no way that this is working. You should use the "mfrc522" at least once inside the "loop" to get the RFID code from the card reader. Currently, you are always comparing the code "EA A3 DB 81" to an empty string. String content = ""; // initilze an empty string content.toUpperCase(); // empty string to upper case is still empty if (content.substring(1) == "EA A3 DB 81") // check if empty string equals "EA A3 DB 81"

[@abobija]

Yup. That's right. Block of code inside of IF condition will never be executed.

[@sbmfighter]

excellent work !

[@Shadow__X]

I think it would be better to use the lock that is already in the door (like with these locking knobs you can get for bathroom doors), instead of making a weak one (compared to main lock)

[@PowerGearPerformance]

Great work!

[@jarisipilainen3875]

secure as hell even lost rfid tag you can break in xD

[@gaby1491]

LMAO

[@Archie_12321]

hey mate thanks a tonne for this, i am making my own version with a remote control and your stl files worth the sub

[@idontmindpineappleonpizza8825]

“Was man” What happened

[@mutated__donkey5840]

*snip*

[@matuhan196]

What if you runout of battery with the door closed?¿

[@maverickstclare3756]

It's plastic, give it a shoulder

[@VINInvents]

How can you unlock and lock the door from the inside?

[@xcruell]

One kick and that lock is *gone* :D

[@charadremur333]

Prevent honest people from doing dishonest things. It is a deterrent.

[@FFlaminscorpion]

Well kappa i guess me and you have to make a steel version/ door

[@xcruell]

@@charadremur333that's a good point

[@xcruell]

@@FFlaminscorpion absolutely my thought

[@FFlaminscorpion]

@@xcruell once i get a job we are doing it, no and, if or buts

[@marukaneko5366]

What happens when you outside locked and the battery dies??? Hmmmmmmm...

[@jarisipilainen3875]

4:47 pushhhh harder..and its glass door xD

[@ayberkatescelik1309]

What an nice work, But when I open arduino code it says "File does not exist" maybe you can generate an new github link or something.

[@ZeroLocc]

I keep seeing people installing door locks with these motorized devices that Take 5 Seconds to open. But all you need is a spring for that Bolt. The bolt and spring go inside of a casing so that when you release the motor the door pops open quickly and when you go to lock the door the motor would take five seconds to lock it when time is not the essence. Does that make sense?

[@maverickstclare3756]

Fun project. Kiitos.

[@denzelsprit5407]

Foot vs. DoorLock

[@alextrezvy6889]

02:27: Why he uses 3 fans instead of 1? Is 1 fan not enough?

[@tbhinteractieve]

Instead of button maybe you could use endstop :)

[@DamjanDimitrioski]

What's the linear shaft Rail rod diameter and length? I can select model from: 6x100 6x200 8x100 8x200?

[@aa-hn2fd]

Can you modify one for me so it attaches to a door knob of any size?

[@cryora]

What if the electrical connections fail and it locks you out?

[@jagr1692]

Could u make a flow switch with a pump I have a desgin

[@CryptoWorld2]

I really thought you were gonna kick the door open at some point lol

[@xavier_le_x]

What will happen when the battery will not be powered enough , when it will be empty ?

[@STOP_RIGHT_THERE_CRIMINAL_SCUM]

if someone kicks the door hard enough, the screws will pull thru the plastic

[@kedarprabhudessai]

Cool... Checkout Spintly access control system

[@markos-bunte-welt]

it's great but there is a small problem how do you get the door open when the battery is empty :-)

[@Slaatje01]

Just kick the door, the plastic lock will break!

[@lensnlarge970]

may i opt for 5v direct current supply instead of battery ?

[@DenzCasuela]

why would you need a breadboard for just that few components

[@gingertimelord5]

I would like to build this for fun, but the code link is dead

[@coelho5br]

What’s the frequency to recharge the battery ?

[@sheet-son]

Bracket is too thin near screws. Would easily break if someone kicked the door

[@TungPham-xd2ho]

When the system fails, how do I get inside the room?

[@dickusbigus2079]

Who tf at KZbin HQ thought double ads is an amazing idea

[@alpha_pixel_]

Cast some metal in that model.. 3d printed parts is 1 push breaking

[@ZGSJHHM]

哈哈，同款步进电机驱动板

[@RenatoGloe]

Hey! The code file is down, could anyone who still have it upload it?

[@justin60222]

What happens if it fails?

The code has lost from location

Great, But it seems tangible

[@muizrazman28]

can i get that 3D print file?

[@mohitawatade]

Just short the two wires coming from inside

[@Alex-sc6yy]

You could have secured it with double sided tape instead of screws lol
