Make an Active Buzzer Beep using Arduino UNO | Do it Yourself Project

Making an Active Buzzer Beep using Arduino UNO:

To make an active buzzer beep using Arduino, we'll need to set up the circuit and program our board.

Components Required:

- 1 * Arduino UNO 
- 1 * USB cable 
- 1 * Active buzzer 
- 1 * 1 kΩ Resistor 
- 1 * NPN Transistor
- 1 * Breadboard 
- Several jumpers wire 

Circuit Diagram:

Procedure:

1. Make the connections according to the circuit diagram.

2. Connect your Arduino UNO to PC.

3. Upload the code provided to the board using Arduino IDE.

4. Enjoy using Active Buzzer.

Code:

int buzzerPin=8; //definition digital 8 pins //as pin to control the buzzer void setup() { pinMode(buzzerPin,OUTPUT); //Set digital 8 port mode, the } //OUTPUT for the output void loop() { digitalWrite(buzzerPin,HIGH); //Set PIN 8 feet as HIGH = 5 v delay(2000); //Set the delay time，2000ms digitalWrite(buzzerPin,LOW); //Set PIN 8 feet for LOW = 0 v delay(2000); //Set the delay time，2000ms }
