Please clarify your specific problem or add additional details to highlight exactly what you need. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help centerplease edit the question. If you don’t have the part number it’s difficult to tell whats the current consumption of the device at the specified voltage.
So what I suggest is. Be sure it’s voltage rating is 5V.
HXD Buzzers 5V
Connect a 5V supply to the buzzer by a small time, it should have polarity marking, respect it. Being it a buzzer, use a current-meter a multimeter in the DC current mA scale for exampleconnecting one point of the multi-meter to the supply, the other to the buzzer, and the other point of the buzzer to the supply, always respecting the polarity.
This will show to you what is the average current consumption of the buzzer. A NPN transistor will help you. A general purpose NPN transistor that can handle the current and voltage can be used, also should have the necessary current gain. It really depends on the buzzer you’re using. Without knowing the part number, you won’t be able to use it properly.
Just as Majenko helped me notice, I’ve never used a buzzer myself though I had, but didn’t – the nomenclature seems to be very confusing.
I’ll show you how I calculate my series resistance for it, just in case yours is similar to one of these.
That’s past its maximum current rating, so we need to take it to a lower level. We need to leave some room below the maximum rated current of 40mA and also stay within safe current levels that the Arduino output pin can source or sink, which is about 20mA. So let’s shoot for that 20mA. But that’s in my case. You need to find your part’s datasheet.
If you have a piezo, you’ll have to find its max rated current and coil resistance and do the math for your part.
Ask your supplier for the datasheet, and if he or she doesn’t have it, ask for the part number and look for the datasheet online. Home Questions Tags Users Unanswered. Buazer ideas on what resistor I should use? Ricardo 4, 14 37 Meletis Flevarakis 3 7 Do you have a part number for the buzzer?
Can you post a picture of your part so we can tell whether what you have is really a buzzer or a piezoelectric transducer? DiegoCNascimento I’ve connected it with 1. hxr

Well connect to a 5V supply, and make a good contact. If you don’t have a 5V supply, try using 3 x 1. If it does not make an audible tone, try rasping the contact, if you ear noise its not a buzzer. Again be sure to respect the polarity. If you are hearing the weird sound even after some time and the contacts are good you are not shaking the contactsits probably a buzzer that is not oscillating as it should because of the low voltage.
But again if i put 5V is it gonna blow up? A NPN transistor will help you simulate this circuit — Schematic created using CircuitLab A general purpose NPN transistor that can handle the current and voltage can be used, also should have the necessary current gain.
Diego C Nascimento 8 According to the datasheet, it’s specs are: If you really have a buzzer, then I won’t be able to help you. What you have there is not a buzzer, but a piezoelectric transducer – a very different thing. A transducer you have to apply a waveform to it to make a noise, like a speaker using the Arduino’s tone function. The problem is people often sat buzzer when they mean transducer.
Put that plate in a little black plastic casing and you have your “buzzer”. It cannot make a tone by itself, you need to oscillate it.
An actual buzzer includes an oscillator to generate the tone so all you need to provide is a voltage. A buzzer has a fixed tone or sound pattern. Some play multiple tones doo-dah-doo-dah and some do various sweeps. These are more often referred to a sirens though. But yes, you can’t change how they sound, but a transducer can make any sound, even play music.
