Electronic door lock system circuit diagram.

The main principle of this circuit is that the door lock opens only when the buttons in series are pressed at a time. One transistor electronic code lock system circuit principle. If any button which is in parallel is pressed door is locked. The circuit requires.

The circuit is very simple and can be assembled using readily available components. This is the circuit diagram electronic door lock security key system. Here an at89c52 microcontroller is used and it is an 8 bit controller. Build an ibutton electronic lock based around a at91c2051 microcontroller includes asm source code circuit schematic schema wiring diagram diy project schaltbild combination lock pic16f84 circuit schematic schema wiring diagram diy project schaltbild.

Schematic of the code lock circuit. Description and working of electronic code lock circuit in the circuit electronic code lock the lock code is set through proper connection of line wires to the pads a b c and d as shown in the schematic diagram of electronic code lock. Electronic door lock home burglary incidents are on the rise. Homes without proper security measures in place are particularly more vulnerable.

The complete phenomenon of electronic code lock system has been described briefly in the further paragraph. The output can be connected to drive the relay to open the door usually using motor. But it is easy to avoid home break ins by using a simple solution electronics projects for you. The lock code can be set by connectiong the line wires to the pads a b c and d in the figure.

The circuit is built around dual j k flip flop 74ls73 ic3 and ic4 regulators 7812 and 7805 ic1 and ic2 respectively 555 timer ic6 and a few other components. It means that this security system circuit is the combination of pressed key itself not the mechanical. This is the complete circuit diagram of the password protected door lock security system designed in cadesoft eagle 9 1 0 version. For example if the code is 1756 connect line 1 to a line 7 to b line 5 to c line 6 to d and rest of the lines 2 3 4 8 and 9 to the reset pad as shown by dotted lines in the schematic.

It is a quite simple circuit of electronic door lock with security code of 7 digits. Password based door lock system using 8051 microcontroller circuit design uses five major components a microcontroller an l293d motor driver a dc motor a 4 4 matrix keypad and a 16 2 lcd. Circuit and working fig. 1 shows the circuit of the electronic door lock.
