The document presents a group project on implementing a NAND gate circuit. It includes: - An introduction to NAND gates and their usage. - A circuit diagram and truth table for a circuit with the equation Y=A.B+C. - A description of the components used - a breadboard, 74LS00 IC containing four NAND gates, resistors, LEDs, wires and a 9V battery. - Steps for constructing the circuit on the breadboard by connecting the IC pins to inputs and outputs and adding an LED and resistor to indicate the output.

3. Topic
Implementation of NAND gate

4. Introduction
 NAND gate is the complement of AND
function, as indicate by a graphic symbol
which consists of an AND graphic symbol
followed by a small circle.
 NAND gate is extensively used as standard
logic gate.
 NAND gate is easily constructed with
transistor circuits.
 Boolean function can be easily implemented
with them.

8. Apparatus
 Breadboard
 74LS00 IC
 10 ohm Resistance
 LED
 Connecting wires
 9v battery

9. Breadboard
Breadboard is a solder less device for temporary prototype with
electronics and test circuit design it consist of many holes.
 Pwer rails
 Connect other components.

10. Breadboard
 The rows of central portion are connected
 Column are not connected

11. 74LS00 IC
 Member of 74XXYY IC series.
 Four NAND gates
 14 pins from which two are used to connect it from
battery terminals which are 7th and 14th pin.
 Input pins
 Output pins

12. 10 ohm Resistance
 Resistor is used to resist electric current
 Consist of two pins

13. LED
 Light emitting diode is a semiconductor light
source that emit light when current flow
through them.
 Two legs
 Larger is Anode
 Smaller is cathode

14. Connecting wires
 The wires used to connect components.

15. 9v battery
 Supply power to circuit
 Enough power to deliver for the required
circuit.

16. Making of circuit
 Take a breadboard pin IC in the center of it .
 Now give two inputs to the first NAND gate by connecting the pin no one and
two of IC .
 Now make single input NAND gate by giving single input to the second
NAND gate on pin no 4 and 5.
 Now the output of these two NAND gate will be the input of third NAND
gate so take output from these two gates by connecting wires and input them
to the third NAND gate at pin no 10 and 9 respectively
 Connect one pin of resistor to the output of third gate at pin no 8 and other to
the positive terminal of LED and ground the negative terminal of LED by
connecting to negative terminal of battery using connecting wire .
 Now connect pin 7 and 14 to negative and positive terminal of battery using
connecting wires respectively
 Now connect 9v battery to the circuit
 Check that the required output is coming out or not by observing the output of
truth table
 Required circuit is ready to present.

17. Conclusion
 The making of NAND gate include 74LS00
IC, brad board, resistance, connecting wire,
LED and battery.
