Rs.520.00 Rs.700.00

The process consists of a logical operation on one or more logical inputs that generate a solitary logic output.
A logic gate is comprised of resistors and transistors, or diodes.
They can perform simple or highly complex operations by joining a variety of logic gates.
This product contains ready to use fully assemble circuit for simple logic gates like "OR", "NOR" and "NAND" gates.
It is a 100% complete working, ready-to-use handmade project.
Utilize electronics circuit made on card board of size 31 cm x 21 cm.
This kit needs battery. Battery is not provided with kit.
Best suited for those who wish to submit a physics science projects in school/college.
Can be used as 'class room teaching aid' or 'science fair/exhibition project.
This product comes with detail printed notes which explains the theory and circuit diagram of the project.

(1) NOR :-

The NOR gate is a digital logic gate that implements logical NOR.
A HIGH output (1) results if both the inputs to the gate are LOW (0); if one or both input is HIGH (1), a LOW output (0) results.
NOR is the result of the negation of the OR operator. It can also be seen as an AND gate with all the inputs inverted.
If anyone of the switch S2/S3 is closed, the transistor corresponding to that turns on and hence the output (v5) goes to low.
The output becomes high only when both the switches are opened.

(2) OR :-

An OR gate is a digital logic gate with two or more inputs and one output that performs logical disjunction.
The output of an OR gate is true when one or more of its inputs are true.
If all of an OR gate's inputs are false, then the output of the OR gate is false.
There are many ways to implement logic gates.
Most frequently it is implemented by transistors. Here we are going to implement two input one output OR logic by using two transistors.
This is based on the principle of transistor switching action.
If any of the switches S2 or S3 is closed, the transistor corresponding to that gets turned on and hence V5 becomes high and LED D1 starts glowing.
The led can be turned off only by opening both switches.

(3) NAND :-

In digital electronics, a NAND gate (negative-AND) is a logic gate which produces an output which is false only if all its inputs are true; thus its output is a complement to that of the AND gate.
A LOW (0) output results only if both the inputs to the gate are HIGH (1); if one or both inputs are LOW (0), a HIGH (1) output results.
If anyone of the switch S2/S3 remains opened, one of the transistors remains off and output remains high and LED glows. Whenever we press.
