Locker Guard Locker Security Alarm Circuit Anti Theft
Locker Guard Circuit Diagram. This compact circuit is designed to protect a locker or almirah from burglary. If the locker is opened while in the armed state, the circuit triggers a loud police siren to deter the burglary attempt.
The Locker...
electronic circuit breaker
A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and, by interrupting continuity, immediately discontinue electrical flow....
Digital Electronic Lock schematic
The digital lock shown below uses 4 common logic ICs to allow controlling a relay by entering a 4 digit number on a keypad. The first 4 outputs from the CD4017 decade counter (pins 3,2,4,7) are gated together with 4...
Electronic Locks Circuits
This circuit is designed to operate an electric strike or an electromagnetic lock on a door. It does not control the door's opening or closing but rather activates a small electromagnetic strike that unlocks the door. The opener features a...
Digital lock 4
The digital lock circuit consists of a timing trigger circuit, a trick lock circuit, a sound and alarm circuit, and a control implementation circuit, as illustrated in Figure 3-101. The timing trigger circuit is made up of transistors V1 and...
Digital Ber-password circuit
The Digital Combination Lock Circuit is a schematic for a simple electronic combination lock utilizing the LS7220 integrated circuit (IC). This password-protected digital lock can activate a relay to control any device by entering a preset combination of four digits....
Key Code Combination High Security Door Lock
This project involves an electronic lock that supports numerous combinations, which can be easily modified. It unlocks only with the correct sequence of four consecutive numbers. A significant feature of this electronic lock is that the four numbers must be...
Electronic Door Lock Security Key
This is the circuit diagram for an electronic door lock security key system. This security system circuit combines a pressed key mechanism (non-mechanical), and the output can be connected to drive a relay to unlock the door.
The electronic door lock...
