We will make this circuit for the '''NAND''' Gate''' '''demonstration'''.'''
|- style="background-color:transparent;border:1pt solid #000000;padding:0.176cm;"
|| Show the diagram

|| To do this experiment, we will need
* <div style="margin-left:1.27cm;margin-right:0cm;">1 AND Gate</div>
* <div style="margin-left:1.27cm;margin-right:0cm;">1 NOT Gate</div>
* <div style="margin-left:1.27cm;margin-right:0cm;">2 Logic Inputs</div>

|- style="background-color:transparent;border:1pt solid #000000;padding:0.176cm;"
||
|| Let us open the '''CircuitJS''' interface.

Click on '''File''' in the menu bar and select '''New Blank Circuit.'''
|- style="background-color:transparent;border:1pt solid #000000;padding:0.176cm;"
|| Click on the '''Draw''' option

Browse through the menu

Draw AND Gate
|| Click on the '''Draw '''menu and select '''Logic Gates, Input and Output'''.

Then select '''Add AND Gate'''.

Drag and draw the '''AND gate''' in the working area.
|- style="background-color:transparent;border:1pt solid #000000;padding:0.176cm;"
||
|| We need two inputs and one output to see the result of the '''NAND''' Gate.
|- style="background-color:transparent;border:1pt solid #000000;padding:0.176cm;"
||

Select Logic Input
|| Go to the '''Draw''' menu and select the''' Logic Gates, Input and Output'''.

Select '''Add Logic Input''' and draw the logic input as shown.

Right click on the logic input and select the '''Edit''' option.

In the pop-up window, check the '''Numeric''' box and click on the '''OK''' button to save the changes.

By doing this, the input values will be shown in either 0’s or 1’s.
|- style="background-color:transparent;border:1pt solid #000000;padding:0.176cm;"
||
|| We need two logic inputs to build the '''NAND''' gate.

Right click on the logic input component and select the '''Duplicate''' option.

Connect both the logic inputs to the '''AND''' Gate as shown.
|- style="background-color:transparent;border:1pt solid #000000;padding:0.176cm;"
||

Select Add Inverter

|| We require a '''NOT''' gate to get the desired output of '''NAND''' Gate.

Click on the Draw menu and go to '''Logic Gates, Input and Output''' and select the '''Add Inverter''' option.

The '''NOT''' gate is named as '''Inverter''' in '''CircuitJS'''.

Drag and draw the '''NOT''' gate in the working area.

Connect the output of the '''AND''' gate to the input of the '''NOT''' gate.
|- style="background-color:transparent;border:1pt solid #000000;padding:0.176cm;"
||

Select Logic Output

|| Now we need a logic output to see the result.

Click on the '''Draw''' menu and go to '''Logic Gates, Input and Output'''.

Select '''Add Logic output''' component from the list.

Drag and draw the Logic output component.

Right click on the Logic output component and select '''Edit''' option.

In the pop-up window, check the '''Numeric''' box and click on the '''OK''' button to save the changes.

By doing this, the output values will be shown in either 0’s or 1’s.

Connect the logic output to the output pin of '''NOT''' gate.
|- style="background-color:transparent;border:1pt solid #000000;padding:0.176cm;"
|| Use Add text option to give labels
|| Use the '''Add text''' option to label these input and output pins.

Let us label the inputs as A and B, and output as Y.
|- style="background-color:transparent;border:1pt solid #000000;padding:0.176cm;"
|| '''NAND Gate Truthtable.png'''

|| This is the truth table for the '''NAND''' Gate, where A and B are the inputs and Y is the output.

If any of the inputs in the '''NAND''' gate is 0, the output is 1.
|- style="background-color:transparent;border:1pt solid #000000;padding:0.176cm;"
||
|| Let us go to '''circuitJS''' simulator to verify the truth table of the '''NAND '''gate.
|- style="background-color:transparent;border:1pt solid #000000;padding:0.176cm;"
||

Working of the circuit
|| For the first condition in the truth table, both inputs A and B are 0, i.e. they are LOW.

By default, the values of both the inputs is 0.

Notice that the output Y in the circuit is showing the value 1, i.e. output Y is HIGH.

Thus the first condition is verified.
|- style="background-color:transparent;border:1pt solid #000000;padding:0.176cm;"
||
|| To verify the second condition in the truth table, we need to change the value of input B.

Click on the input B value, and notice the input value changes from 0 to 1.

The result at the output Y is still the same. i.e. output Y is 1.

The second condition from the truth table is verified.

Check the remaining two input conditions of the '''NAND''' gate with the truth table.
|- style="background-color:transparent;border:1pt solid #000000;padding:0.176cm;"
|| Slide:

'''Symbol_NAND Gate.png'''
|| '''NAND''' Gate is represented with this symbol.

Note the small circle added in the '''AND''' gate which represents the '''NAND''' gate.
|- style="background-color:transparent;border:1pt solid #000000;padding:0.176cm;"
||

|| In '''CircuitJS''', a '''NAND''' gate component is available.

Let us see how to use it.

Go to '''Draw''', then select '''Logic Gates, Input and Output''', and then select the '''Add NAND''' gate option.

Drag and draw the gate in the working area.
