Simple Code Lock Circuit ElectroSchematics This simple code lock circuit described here is of an electronic combination lock for daily use. It responds only to the roght sequence of four digits that are keyed in remotely. If a wrong key is touched, it resets the lock. The lock code can be set by connectiong the line wires to the pads A, B, C and D in the figure. 555 Timer Based Simple Electronic Code Lock Circuit 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. Simple Electronic Code Lock | Circuits Projects Simple Electronic Code Lock Circuit Diagram: The code lock circuit is built around two CD4013 dual D flip flop ICs. The clock pins of the four flip flops are connected to A, B, C and D pads. The correct code sequence for energisation of relay RL1 is realised by clocking points A, B, C and D in that order. NTE Electronics Circuit: Simple Electronic Code Lock Simple Electronic Code Lock The circuit diagram of a simple electronic code lock is shown in figure. A 9 digit code number is used to operate the code lock.When power supply to the circuit is turned on, a positive pulse is applied to the RESET pin (pin 15) through capacitor C1. Simple Electronic Lock Project Electronics Club Project Simple Electronic Lock Project. Download a PDF version of this page: Simple Electronic Lock Project (PDF) There are six (or more) push switches. To 'unlock' you must press all the correct ones at the same time, but not press any of the cancel switches. Pressing just one cancel switch will prevent the circuit unlocking. One Transistor Electronic Code Lock System Circuit Diagram One Transistor Electronic Code Lock System Circuit Principle: The main principle of this circuit is that the door lock opens only when the buttons in series are pressed at a time. If any button which is in parallel is pressed door is locked. When all these buttons are pressed transistor switches the relay and the door is opened.

Electronic Lock Circuits Code Lock with ATMEL AVR CodeLock AVR electronic combination lock is realized with Atmel AVR microcontroller AT90S2313 or ATtiny2313. Program in hex code is 2 kB long. User code is consisted of 1 to 4 digits. If you buy the chip than user code is consisted of 1 to 8 digits. Electronic Simple Code Lock For Daily Use The electronic simple code lock circuit described here is of an electronic combination lock for daily use. It responds only to the right sequence of four digits that are keyed in remotely. It responds only to the right sequence of four digits that are keyed in remotely. 555 timer circuit electronic key code lock An essential property of this electronic code lock is that it works in monostable mode, i.e. once triggered, the output becomes high and remains so for a period of time, governed by the timing components, before returning to the quiescent low state. Electronic bination Lock | Detailed Circuit Diagram ... This 7 digit electronic combination lock can be easily hard wired for any combination that you choose. The circuit uses a 4 bit, divide by 8 Johnson counter (IC1), ten push button switches and NPN transistor T1. When switch S2 is pressed, transistor T1 conducts and capacitor C2 discharges via diode ... Electronic lock The most basic type of electronic lock is a magnetic lock (informally called a "mag lock"). A large electro magnet is mounted on the door frame and a corresponding armature is mounted on the door. When the magnet is powered and the door is closed, the armature is held fast to the magnet. Mag locks are simple to install and are very attack resistant. Codelocks Specialists in design, manufacture and ...
