Arduino for Beginners - 2022 Complete Course - Add a Potentiometer to Your Circuit

The video tutorial demonstrates how to use Tinkercad and real hardware to set up a circuit with a potentiometer. It covers duplicating a push button circuit, understanding potentiometers as variable resistors, and connecting them to a circuit. The tutorial also explains the real circuit setup, ensuring proper connections on a breadboard, and highlights the importance of organizing components for future additions.

What is the purpose of using Tinkercad in this tutorial?

• To simulate the circuit before building it with real hardware.

• To create 3D models of the components.

• To design a new type of LED.

• To test the durability of the components.

What is the primary function of a potentiometer in a circuit?

• To store electrical energy.

• To act as a variable resistor.

• To convert AC to DC.

• To provide a constant voltage.

Which resistance value is commonly used for a potentiometer in starter kits?

• 10K ohm

• 5K ohm

• 1K ohm

• 20K ohm

How should the terminals of a potentiometer be connected in a circuit?

• One terminal to ground and the other to an analog input.

• Both terminals to ground.

• Both terminals to 5 Volt.

• One terminal to ground and the other to 5 Volt.

Which pin of the potentiometer is connected to an analog input pin?

• Terminal 1

• Terminal 2

• The middle pin (wiper)

• All pins

Why is it important to disconnect the USB cable before setting up the real circuit?

• To prevent electrical shock.

• To ensure the circuit is not powered during setup.

• To avoid short circuits.

• To save power.

Why is the potentiometer placed close to the push button in the real-world setup?

• To improve the circuit's efficiency.

• To save space for additional components.

• To ensure it is not affected by other components.

• To make it easier to manage.
