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

This video covers the basics of setting up a circuit using Tinkercad, including components and wiring.

What is the purpose of duplicating an existing circuit in Tinkercad?

• To create a new circuit based on the original

• To create a backup of the original circuit

• To delete the original circuit

• To modify the original circuit directly

Why is it important to use color conventions for wiring?

• To confuse the user

• To match the colors of the components

• To easily identify different types of connections

• To make the circuit look colorful

What is the role of a pull-down resistor in a circuit?

• To increase the voltage

• To connect the circuit to the power supply

• To decrease the current

• To stabilize the default state of a button

How does a pull-down resistor affect the state of a push button?

• It increases the button's resistance

• It makes the default state high

• It makes the default state low

• It disconnects the button from the circuit

Which pin on the Arduino is used to read the state of the push button?

• Ground pin GND

• Power pin 5V

• Digital pin #2

• Analog pin A0

What is the purpose of connecting the 5 Volt line to the breadboard?

• To ground the circuit

• To reduce the voltage

• To disconnect the circuit

• To power the entire circuit

What should be done before finalizing the hardware setup?

• Test the circuit with a multimeter

• Connect the Arduino to the power supply

• Disconnect the Arduino board

• Add more components to the circuit
