555 Timer Based Simple Electronic Code Lock Circuit In this simple circuit we are building 555 Timer IC based Code Lock. In this Lock, there will be 8 buttons and one needs to press specific four buttons simultaneously to unlock the Lock. The 555 IC is configured as a Monostable Vibrator here. Electronic Code Lock Circuit Engineering Projects 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 circuit. For clear understanding, an example might be more appealing. Electronic Code Lock Circuit Implementation ... Code lock described here is an electronic combination lock which can be used in daily life. The circuit is described here has following main advantages 1 It is built using transistors and few more components; therefore small in size can be easily mounted on the doors. 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. One Transistor Electronic Code Lock System Circuit Diagram One Transistor Electronic Code Lock System Circuit Design:. The circuit consists of a stepdown transformer whose input is AC supply of 230V and 50HZ. In the stepdown transformer, number of windings in the primary coil is less than the number of windings in the secondary coil. Electronic Code Lock Circuit Diagram Best Place to Find ... Electronic code lock circuit diagram The door key operates a switch which controls the electrical supply that actuates the door lock block circuit diagram for remote central locking the encoded signals that are transmitted by the Basic general wiring diagram for the sts.
