Getting started with the Buzzer – 5V
Making sound on the Arduino is an interesting project, this con be accomplish using different modules and devices depending on your project and choices. In this project, we’ll be looking at the way you can make sound with a buzzer. Buzzer used by hobbyist come in two types: The active buzzer and the passive buzzer. For this project, we are going to be using an active buzzer. Check out my tutorial on using a passive buzzer.
An active buzzer will generate a tone using an internal oscillator, so all that is needed is a DC voltage. To generate tone with an active buzzer, all you need is a DC voltage. Most active buzzer can be powered with 3-5V.
An active buzzer can be controlled from an Arduino pin, very similar to the way you turn on and off an LED using digitalWrite.
NOTE: Its not advisable to control the buzzer using analogWrite i.e. PWM.
Hardware required
- Arduino UNO
- 5V Buzzer
- Jumper
- Breadboard
Connecting the Hardware
Arduino Uno Buzzer
GND GND (The short leg)
D5 Vcc (The long leg)
Upload the Code
#define buzzerPin 5
void setup() {
pinMode(buzzerPin,OUTPUT);
}
//The buzzer on for 1 second and off for 1 second
void loop() {
delay(1000);
digitalWrite(buzzerPin,HIGH);
delay(1000);
digitalWrite(buzzerPin,LOW);
}
RESULTS
The buzzer will be on for 1 second and off for 1 second.
