Buzzer 5V

Description

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);}
