- 1Caution 2Step 1: Build the circuit, as illustrated in Figure 1, with the matching schematic diagram of Figure 2.
3) Step 2: Set the key code for the system by configuring the four key code switches.
4) Step 3: Set the data entry switches to match the key code. How do digital locks work?
Like any other door lock, digital locks also use a latch or a bolt, which runs from the door and the doorframe to prevent access.
However, these locks use an electronic or battery-operated system to control the bolt where the motor in these digital locks requires an electronic impulse..

How do you make an electronic combination lock?
An electronic lock or digital lock is a device which has an electronic control assembly attached to it.
They are provided with an access control system.
This system allows the user to unlock the device with a password.
The password is entered by making use of a keypad..
What are the advantages of using electronic locks?
An electronic lock or digital lock is a device which has an electronic control assembly attached to it.
They are provided with an access control system.
This system allows the user to unlock the device with a password.
The password is entered by making use of a keypad..
What is a 555 based code lock?
These locks are mostly built using microcontrollers but can also be made using a 555 IC.
Here, the LED represents the Electric Lock, which remains locked when there is no current and gets unlocked when the current passes through.
The combination of definite four buttons is the “Code”, which is needed to open the Lock.Jan 24, 2020.

What is electronic code lock?
Prepare a truth table with A, B, C and D as four inputs resulting in 16 possible combinations (optional).Convert the truth table information into a Boolean expression.
Form the Minterm Boolean expression for the electronic lock circuit..
What is electronic combination lock?
Mechanical combination locks usually have a dial that is rotated to three different numbers (four numbers on some safe locks) to open the lock.
Electronic combination locks usually have a keypad where the combination can be entered like a telephone number..
What is electronic lock using basic logic gates?

Form the Minterm Boolean expression for the electronic lock circuit..
What is electronic lock using basic logic gates?
The physical keys might get lost, duplicated, or stolen.
In either case, traditional locks are easy to be deceived.
Digital smart locks, on the other hand, provide a high level of security with additional features such as limited access, biometric identification, and an intelligent locking system..

- An electronic lock (or electric lock) is a locking device which operates by means of electric current.
Electric locks are sometimes stand-alone with an electronic control assembly mounted directly to the lock. - The timer based code lock circuit is built around a single IC that is NE555 timer which works in mono-stable mode.
In mono-stable mode IC is once trigged it will hold the output for a specific interval of time as defined by the timing component before returning to its original state. - These locks are mostly built using microcontrollers but can also be made using a 555 IC.
Here, the LED represents the Electric Lock, which remains locked when there is no current and gets unlocked when the current passes through.
The combination of definite four buttons is the “Code”, which is needed to open the Lock.Jan 24, 2020 - What are digital locks? Electronic or Digital locks are electronic or battery-operated locks that do NOT require the use of physical keys for access.
They're used as an alternative to the conventional mechanical locks, with the automated features giving a more creative security solution depending on its intended use.
