Secret Electronic Lock Without Visible Interface 5 Steps Circuit Diagram Electronic Safe: Overview This is a simple electronic safe. It will consist of a 3d printed safe coupled with an Arduino at the center of the electronic access system. Adjust the height so the switch so the circuit closes when the door closes and opens when the door opens. It will be easier to connect wires to the switch before installing Digital Code Locks are very popular in Electronics, where you need to enter a particular 'Code' to open the Lock. This type of Locks needs a Microcontroller to compare the entered code with the predefined code to open the Lock. We have already built these kinds of Digital Locks using Arduino, using Raspberry Pi and using 8051 microcontroller. But today here we are building the Code Lock
Then a circuit to save each pressed number and toggle between displays ; As well as an internal memory for our password ; And, the hearth of our lock, the comparator (its 8 bits ยดcause there are 4 bits per digit in the display, meaning that if you want to do a 4 digit lock you will need two of this connected together.)
Digital code lock circuit without using Microcontroller Circuit Diagram
The project is simple and easy; Applications. This simple timer-based electronic code lock circuit has usage in residential places to ensure better safety. It has been used by organizations to ensure authorized access to highly secured places. With a slight modification, this will control the switching of loads through a password. This electronic code lock circuit is characterized by its basic design employing a notable code implementation with just a single active component and a minimum of 8 button switches.. How does the circuit of the code lock operate? In order to activate the relay, all four buttons S1 to S4 need to be pressed simultaneously.. If any of the buttons from S5 to S8 are pressed, the relay remains
Default Password: 21345. Circuit Description: The proposed electronic lock circuit consists of just few components; an IC 4017 which is the heart of the circuit, 11 push buttons for entering the pin number, 5 diodes to prevent short-circuit between output pins, couple of LEDs for indicating the status whether the circuit is locked or unlocked, couple of pull-down resistors, couple of current Now with the rapid growth of technology, our locking systems are also modernized. New, better and more functioning Digital code lock have taken the place of old traditional locks, because it is small, secure and reliable than its mechanical counterpart. In this project we will see how to make this digital code locker without using MCU. This would signal everyone in the area that someone is tampering with your safe, and allow you to react accordingly. Like my previous project, I will be creating this circuit within TinkerCAD, a free-to-use online modelling program that allows you to create circuits electronically. However, since this instructable is still based off a circuit
