|| Assume that we have forgotten to make the potentiometer ground connection while creating the circuit.

Select the ground wire connection and right click and select delete.

Otherwise, press the delete button to delete the ground connection.

Now let us check the output.

|| Click on the '''Start Simulation'''. The code will compile properly and it will show there are no errors.

Let us check the rotation of the servo motor.

|| Note that the servo motor is not changing its shaft position as expected.

Hence you have to cross check all the required pins are connected correctly in the circuit.

Type servo motor

Click on the '''Download Project '''button.

save the file in downloads folder
|| To download the JSON file of this project, click on the''' Export JSON file''' icon on the top toolbar.

Let us give '''Servo_motor '''as the filename to save.

Click on the '''Download Project '''button.

Select the path where you want to save the '''JSON''' file and click on the '''save''' button.

Click on the '''new project''' icon on the toolbar.

Click on the''' Import JSON file''' icon.

Select the '''Servo_motor.json''' file which we saved earlier and click on the open button.

<span style="background-color:#ffffff;">We can see the circuit has been imported. Click on the </span><span style="background-color:#ffffff;">'Code' icon. </span>

Even the code has been imported successfully.

Click on the '''Start Simulation '''button and verify the rotation of Servo motor using the potentiometer.

We can see the imported JSON file is also working properly as expected.
