Project Idea: Door Lock Security System | Arduino

In this video, I will present to you a project idea. Lets call it a Door Lock Security System. The idea here is to control the door lock using an Arduino board. Anyone who wish to enter is requested to input the user password. If the input password is correct, it will trigger the servo motor to unlock the door for some time then it will automatically lock again while 3 consecutive incorrect password will trigger an alarm. The alarm can only disabled by entering the admin password.

Definitely trying this out soon! Thank you ❤️

[@TechToTinker]

Yeah sure why not? :)

[@michaelangelocipat4232]

Nice! Planning to use solenoid lock. Thanks!

[@TechToTinker]

Hi Michael, yes solenoid lock is better for this application. By the use separate external power supply for solenoid lock

[@mseroglu47]

If we want to change the password, is it possible to log in with the keypad and save it to the Arduino memory? Without connecting a computer.

[@KeishaVLacay]

how about if youre going to use 12v solenoid lock sir?

[@dragoplayz25]

@TechoToTinker. Can you modify it something like changing password in keypad .Because I want this project for my school exhibition which is after 5 days. Pls help me as soon as you can. Pls pls

[@aqilahusna17]

can i know which potentiometer you use in this video?

[@TechToTinker]

Hi, any potentiometer you have will do(can be use). Cheers

[@dragoplayz25]

@TechToTinker. How can make the servo move more? can you please tell the change in the code. please please help me

[@TechToTinker]

There is a loop under the function manage status, the pos variable is angle of rotation for the servo

Can I use this project with an MSP430 launchpad and use Energia?

[@TechToTinker]

Hi @Jordan Deneus, definitely possible. You will need to convert the concept to be compatible with other development platform however I don't have experience with MSP430 so I can't help you further.

I don`t have 560 ohms resistor. Can I use 330 ohms resistor?
The screen in not lighting up!

[@ShiveX84]

I checked the connections.

[@dragoplayz25]

@TechToTinker. I tried it but my LCD is not printing any message and servo is not moving

[@TechToTinker]

@HARSHA SHENOY, try to double check the circuit connection

[@vinayachandra5258]

thank you bro
IMADE THE PRIJECT

[@TechToTinker]

@vinaya chandra, wow that's great bro. Keep it up. Thank you for letting me know

[@ExplainingMathematics]

How add new user ?

[@TechToTinker]

Create a password array

[@ExplainingMathematics]

@@TechToTinker you avoiding the question

[@michaelfoo5136]

Why my lcd display does not display anything?

[@TechToTinker]

Check again your circuit connection.
