OTP Based Door Lock Using Arduino And SIM800L
Вставка
- Опубліковано 22 сер 2024
- In this video, we will guide you through the process of creating an OTP (One-Time Password) based door lock system using Arduino and various components like I2C 16x2 LCD, relay, 4x4 keypad, and GSM SIM800L module. The system will enhance the security of your doors by requiring a unique password each time someone wants to gain access.

Nice project sir❤️
Love from Bangladesh 🇧🇩🇧🇩🇧🇩🇧🇩
Is the otp code generates by lock or by cloud server? Typically, the lock is offline and no way to send SMS.
GOOD
Sir can we use a bluetooth module instead of a GSM module for this project ?
My favourite is fingerprint lock :D
sir,when can we add 5 mobile number in program, it will work?
Sir nice project can you provide components list
can you tell me how to change IR to RFID and also the code and circuit drawing
brooo i need your help in my next project i also make a door lock system using fingerprint sensor but i wanna modefy my project by using some sensor so i need your help urgently
please change voice/musik volume = 50/50 to voice/musik volume = 70/30
for gsm sim800l,it must need a sim card?
yes
Sir can we use a bluetooth module instead of a GSM module for this project ?
Used it no issues
Sir can we use 12v 1amp instead of 12v 2 amp..?
Yes
hiii sir i need some help of you
in our college we have to do some project like a smart lock with otp and motion detection can you help us
Mail me
Sir while programing the error is...
Class liquidcrysral I2c has no member named init...
What is the error sir..?
Used another library 📚
Sir I am making this as a project so first I have buy all the components and now I have made all the connection as per circuit diagram and insert the code in Aurdino with no error
But sir GSM Model is not blinking as ??
What to do sir
Yes you can
Sir how can we contact you as clear our doubt
otp is not sending to the phone
Hello sir used to PC software
Sir could you please share the circuit design as a file from designing software it is available as a png file so we couldn't access any of its components, it would be good if you share the design file from the software and also please share the name of the Software which you used for this design.
SIR we are getting a problem in compiling the code.. It says the liquid crystal I2c has no file or directory.. Could you please guide us
Install i2c library
The exact name and model of the component are required.
sir, can i have the component list including model name
Bro, How much cost it takes to completely do this project?
Not much
@@JustDoElectronics approximately range?
How to insert code in hardware
Sir can you plz guide us
yes
sir circuit diagram clear kar dijiye please
How to replace IR sensor with switch
Disconnect it
@@JustDoElectronics will code remain same or any change?
@atikpathan9693 changes
green or red led kaise lagaya
I need components exact name and model
Kindly provide circuit diagram and code sir

@@JustDoElectronics could I modify the code to be otp but not send the code, for like a prize locker. Random code lucky person enters the correct one wins. Not that there will be a prize in what I’m planning, I just want to see if I can make a puzzle box and irritate my co workers.
