This is a round buzzer that operates around the audible 2kHz range. You can drive it directly from a 5V PIC or arduino to generate the tones.
Resonant Frequency: 2300 +/- 300 HZ
Rated Voltage: 5V
Voltage range: 4 : 8 V
Rated Current: 30 ma
Min Sound output at 10 cm: 85 dB
How to connect with Arduino up
Connect one side to ground, and the other side to one of the digital pins on your Arduino via a 100 Ohm resistor. Using the tone() function will make the buzzer sound. Example code is below:
Example code
void setup() {
pinMode(8, OUTPUT);
}
void loop() {
tone(8, 2093, 4);
delay(1000);
noTone(8);
delay(1000);}
