Buzzer¶
The passive buzzer can generate tones of different pitches and durations. By controlling frequency, you can play simple sounds, melodies, or alerts in your projects.
What It Does¶
This example makes the buzzer play tones at different frequencies, allowing you to create beeps or simple music. It’s a fun way to combine coding with sound output.
Real-World Applications¶
Buzzers are found in almost every electronic system where sound feedback is needed:
- 🔔 Alarms & Alerts – Door alarms, smoke detectors, and timers.
- 🎵 Musical Projects – Simple games, learning tools, or electronic instruments.
- 🕹️ Interactive Systems – Sound feedback for buttons or sensors.
- 🏠 Appliances – Microwave beeps, washing machine alerts, or reminders.
- 🤖 Robotics – Sound signals for status updates or warnings.
With a buzzer, students learn how to add sound feedback that makes their prototypes more interactive.
✅ Once you can play tones, try creating sound effects, melodies, or alarms that respond to sensor inputs, making your projects more dynamic.
