LOGIC GATES ANALYZER USING MICROCONTROLLER


AIM:


The main aim of the project is to design a system for
logic controller

using microcontroller.

PURPOSE:



The main purpose of the project is to design a system for
logic controller

using
microcontroller. It
is used to design a system which can be used to analyze different Digital Logic
Gates like AND, OR, NOT, NAND, NOR.

Description:


Now
a day's engineering colleges are increasing in number day by day
which also increases the need for Laboratory equipment. Here is a project which fulfils the
requirement by providing Laboratory equipment for Digital Electronics Laboratory.

Here is a projec
t which is designed around a microcontroller as a control unit. The
aim of the project is to design a system which can be used to analyze different Digital Logic
Gates. This project will enable the user to realize 2
-
input Logic Gates. The inputs can be
giv
en from the switches and the output is shown using indicators.




According to this project, firstly the user needs to select the required
Logic Gate by selecting a particular switch. After that he needs to give inputs for that Logic
Gate with respective switches. The inputs are taken by the microcontroller; analyzes the
Logical Output according to the Logic Gate being selected and outputs the same using
indicators. The hardware involved in the project is Power supply, Microcontroller,

Switches
and output & input indicators.
