Simple Security System Using Logic Gates

The output is high only if both of the inputs are high.

Simple security system using logic gates.

Simple password lock system using logic gates digital system miniproject duration. 4 bit password security system using xor and nor digital logic design 2. Logic gates are the basic building blocks of any digital system. Before using this security system make sure that loops shown in fig.

2 shows the proposed wiring diagram for the loops around the premises. 1 shows the circuit of the digital security system while fig. You can create a three input and gate by using two two input and gates for example. The relationship between the input and the output is based on a certain logic.

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. Based on this logic gates are named as and gate or gate not gate etc. It is the nature of an xor gate to output a high 1 signal if the input signals are not the same logic state. A burglar alarm system for a bank is to be operative only if a master switch at the police station has been turned on.

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. I have complied this list from different resources. 2 are connected as shown in fig. It is an electronic circuit having one or more than one input and only one output.

The digital security system circuit. Digital logic design projects list with logic gates for beginners. The idea is of this system is that the 4 switches key code switches acts as holding the correct password for unlocking the lock. Functioning of these circuits is very easy when we will receive.

A two input and gate is an electronic logic gate that has two inputs and one output. Also read the interesting post pull pin security alarm system. Output is based on the voltage on pin 5. 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.

And gates can be used in a home alarm system. Security system using xor nor 1. 1 4 bit password security system using nor xor. At the time when power supply is attached to the circuit pin 5 voltage is at zero as loop is unbroken.

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