Simple Security System Using Logic Gates

Digital logic design projects list with logic gates for beginners.

Simple security system using logic gates.

Security system using xor nor 1. It is an electronic circuit having one or more than one input and only one output. Ra r 5 447 views. 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. 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. 2 are connected as shown in fig.

You can create a three input and gate by using two two input and gates for example. Also read the interesting post pull pin security alarm system. 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. The relationship between the input and the output is based on a certain logic.

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. 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. The digital security system circuit.

Before using this security system make sure that loops shown in fig. Logic gates are the basic building blocks of any digital 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. 1 shows the circuit of the digital security system while 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. 4 bit password security system using xor and nor digital logic design 2. The output is high only if both of the inputs are high.

Based on this logic gates are named as and gate or gate not gate etc. Output is based on the voltage on pin 5. Dld project submissing to chowdhury akram hossain aiub. And gates can be used in a home alarm system.

Here the inputs for the various sensors placed on the home s.
