System Requirement

Let us open the circuitjs interface.

Click on the File menu and select New Blank Circuit.

Click on the Draw option

Browse through the menu

Click on the Draw menu.

Go to the Passive Components, and then select Add Switch.

Drag and place the switch in the working area.

In this circuit, this switch acts as INPUT for the NOT Gate.

Go to Draw, and select the Add Resistor option.

Drag and draw the resistor.

Change the resistor value to 220 Ohms using the Edit option.

Place the resistor as shown.

Show the path to find the DC power supply and draw it

Now we need a DC Power supply to make the circuit work.

Click on Draw, then go to Inputs and Sources.

Select Add Voltage Source (2-terminal), and drag the DC power supply.

Place the DC power supply across the switch as shown.

We need an LED to show the output of the circuit.

Click on the Draw menu and go to the Outputs and Labels option and

select Add LED.

Now click and drag to draw the LED in the working area.

We have all the required components in the working area.

Now let's connect the components using wires to complete the circuit.

Use the Add Text option to label the switch and LED.

Name the switch as A and the LED as Y in the circuit.

NOT Gate Truth Table.png

This is the truth table for the NOT Gate, where A is the input and Y is the output.

When the input is 0, the output is 1, and vice-versa.

For this, we have to open switch A in the circuit.

Click on the center of the switch to open it.

Now we can see that the output LED is glowing.

This indicates that the output Y is 1, as given in the truth table.

Thus the first condition is verified.

Assignment

Click on Draw, Go to Logic Gates, Input and Output.

Select the Add Inverter option.

The NOT gate is named as Inverter in CircuitJS.

Click and drag the cursor in the working area to draw the NOT gate.

Click on Draw, Go to Logic Gates, Input and Output.

Select Add Logic Input option.

Click and drag the cursor in the working area to draw the logic input.

Press the Esc key to deselect the component wherever required.

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.

Connect this logic input to the input pins of the NOT gate as shown.

Next we will add one logic output to the NOT gate.

Now, go to Draw, click on Logic gates, Input and Output.

Then Select Add Logic output and draw it in the working space.

Right click on the logic output 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 output value will be shown in either 0’s or 1’s.

Connect the logic output to the output pin of NOT Gate.

Use the Add text option to give labels to pins as shown.

Input is denoted by A and output is denoted by Y.

To change the state of the input value from 0 to 1 or vice-versa, click on the input value.

Now click on the input A to make its value 1.

Notice the output value Y is Zero.

For the NOT gate, the output value will always be opposite of the input value.
