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.
