Simple Security System Using Logic Gates

Output is based on the voltage on pin 5.

Simple security system using logic gates.

Logic gates are the basic building blocks of any digital system. Functioning of these circuits is very easy when we will receive. 1 4 bit password security system using nor xor. The relationship between the input and the output is based on a certain logic.

Security system using xor nor 1. Again the purpose of the experiment is not to make a real security system but merely to introduce you to the principle of xor gate code comparison. 2 are connected as shown in fig. 4 bit password security system using xor and nor digital logic design 2.

And gates can be used in a home alarm system. Based on this logic gates are named as and gate or gate not gate etc. You can create a three input and gate by using two two input and gates for example. Subject to this condition the alarm will ring if the vault door is disturbed in any way or if the door to the bank is opened unless a special switch is first operated by the security guard s key.

It is the nature of an xor gate to output a high 1 signal if the input signals are not the same logic state. Also read the interesting post pull pin security alarm system. The idea is of this system is that the 4 switches key code switches acts as holding the correct password for unlocking the lock. Before using this security system make sure that loops shown in fig.

I have complied this list from different resources. A two input and gate is an electronic logic gate that has two inputs and one output. Here the inputs for the various sensors placed on the home s. 1 shows the circuit of the digital security system while fig.

The digital security system circuit. It is an electronic circuit having one or more than one input and only one output. A burglar alarm system for a bank is to be operative only if a master switch at the police station has been turned on. The output is high only if both of the inputs are high.

Dld project submissing to chowdhury akram hossain aiub. 2 shows the proposed wiring diagram for the loops around the premises. 6 bit password based security system using logic gates duration. Simple password lock system using logic gates digital system miniproject duration.

At the time when power supply is attached to the circuit pin 5 voltage is at zero as loop is unbroken.
