Based on this logic gates are named as and gate or gate not gate etc.

Simple security system using logic gates.

The relationship between the input and the output is based on a certain logic. Digital logic design projects list with logic gates for beginners. Dld project submissing to chowdhury akram hossain aiub. The idea is of this system is that the 4 switches key code switches acts as holding the correct password for unlocking the lock.

1 shows the circuit of the digital security system while fig. Ra r 5 447 views. At the time when power supply is attached to the circuit pin 5 voltage is at zero as loop is unbroken. This is a complete list of digital logic design projects for those who want to learn about digital logic circuit and want to design digital logic circuit for their project.

6 bit password based security system using logic gates duration. 2 shows the proposed wiring diagram for the loops around the premises. 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 an electronic circuit having one or more than one input and only one output.

Functioning of these circuits is very easy when we will receive. Output is based on the voltage on pin 5. It is the nature of an xor gate to output a high 1 signal if the input signals are not the same logic state. 4 bit password security system using xor and nor digital logic design 2.

Here the inputs for the various sensors placed on the home s. Simple password lock system using logic gates digital system miniproject duration. A two input and gate is an electronic logic gate that has two inputs and one output. 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. A burglar alarm system for a bank is to be operative only if a master switch at the police station has been turned on. 1 4 bit password security system using nor xor. Security system using xor nor 1.

You can create a three input and gate by using two two input and gates for example. I have complied this list from different resources. Logic gates are the basic building blocks of any digital system. Before using this security system make sure that loops shown in fig.

And gates can be used in a home alarm system.
