Shop Buzzers by Type

Our buzzer range may include products such as:

• Active Buzzers: Buzzers with built-in oscillation circuitry that produce a tone when powered.
• Passive Buzzers: Buzzers that require a signal or PWM output to generate tones, beeps or simple melodies.
• Buzzer Modules: PCB-mounted buzzer modules designed for easy connection to Arduino, ESP32 and other microcontroller boards.
• Piezo Buzzers: Compact sound components used for beeps, alarms, alerts and electronics projects.
• Alarm Buzzers: Sound output components used in timers, warning circuits, access control projects and simple alert systems.

Buzzers for Arduino, ESP32 & Electronics Projects

Buzzers are commonly used in electronics projects where a simple sound is needed. They are useful for timers, alarms, keypad feedback, warning indicators, sensor alerts, robotics, access control, test circuits and educational projects.

Active buzzers are usually easier to use because they produce a sound when voltage is applied. Passive buzzers allow more control over tone and frequency, but they need a suitable signal from a microcontroller. Always check the voltage, current draw, polarity, sound type, pinout and whether the buzzer is active or passive before ordering.

Active vs Passive Buzzers

An active buzzer contains internal circuitry and normally makes a fixed tone when powered. A passive buzzer acts more like a small sound element and needs a changing signal to produce sound. Passive buzzers are often used when a project needs different tones or simple melodies.

Frequently Asked Questions

Do you sell buzzers for Arduino and ESP32 projects?

Yes. AuscomTech stocks active buzzers, passive buzzers and buzzer modules suitable for Arduino compatible boards, ESP32, Raspberry Pi compatible boards and general electronics projects depending on current availability.

What is the difference between an active and passive buzzer?

An active buzzer usually makes a tone when powered. A passive buzzer needs a signal, often PWM, to generate sound and can be used for different tones or simple melodies.

Can I connect a buzzer directly to a microcontroller pin?

Some low-current buzzers may be suitable, but many projects should use a transistor, driver circuit or module depending on current draw and voltage. Always check the buzzer specifications before connecting it.

Are buzzers the same as speakers?

No. Buzzers are mainly used for beeps, alarms and simple tones. Speakers are better for voice, music, sound effects and fuller audio output when used with a suitable amplifier.

Can you help me choose the right buzzer?

Yes. If you are unsure which buzzer suits your project, contact AuscomTech with your controller board, supply voltage, sound requirement and whether you need a simple beep or controllable tones.
