Mission Briefing
By the end of this mission, you will be able to:
Explain what a buzzer is and how it creates sound
Describe the difference between an active and a passive buzzer
Use digitalWrite() to turn a buzzer ON and OFF
Build and code a circuit that beeps on a timer
Have you ever wondered how robots, alarms, and toys make beeping sounds? In this lesson, you'll meet the buzzer, a small electronic component that can create fun sounds and alerts. You'll learn how to use a digital output to turn the buzzer ON and OFF, making it beep whenever you want.
Robo says: “Every great sound project starts with a single beep. Let's wire up a buzzer and give your circuit a voice.”
