Raspberry Pi and Arduino - Go to The Next Level - Buzzer - Circuit

The video tutorial explains how to add a buzzer to a circuit. It covers the steps to connect a buzzer, also known as a Piezo, to a digital pin on an Arduino. The tutorial highlights the difference between passive and active buzzers, emphasizing the importance of using a passive buzzer. It provides detailed instructions on connecting the positive and negative pins of the buzzer to the appropriate points in the circuit, ensuring proper functionality.

What is the first step in connecting a buzzer to a circuit?

• Use a resistor with the buzzer

• Ensure the buzzer is active

• Connect the negative pin to the ground

• Connect the positive pin to a digital pin

Which digital pin is used in the example for connecting the buzzer?

• Pin 2

• Pin 4

• Pin 8

• Pin 10

Is a resistor necessary when connecting a buzzer to the circuit?

• Only if using an active buzzer

• Only if using a passive buzzer

• No, not in this setup

• Yes, always

How can you identify a passive buzzer?

• It has a green or similar PCB

• It requires PWM

• It is larger in size

• It has a black PCB

Why is it important to use a passive buzzer in this setup?

• It does not require PWM

• It is more durable

• It is louder

• It is cheaper
