Project Introduction

This is a simple project that utilizes the use of Buzzer with arduino uno. Buzzer connected to arduino uno board serves as a medium that can convert electrical signals into vibrations of sound. Where Arduino As a power source that controls the Tone that will come out. Controlling the tempo and the outgoing tone Buzzer can produce music or rhythm like a musical instrument.

Component Description

Arduino Uno - is a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.(Source : Arduino.cc )

Buzzer - A buzzer or beeper is an audio signalling device, which may be mechanical, electromechanical, or piezoelectric (piezo for short). Typical uses of buzzers and beepers include alarm devices, timers, and confirmation of user input such as a mouse click or keystroke.(Source : Wikipedia)

Step 1 : Prepare All Parts

You can buy from online store or directly to the Electronics Shop

Step 2 : Build Circuit Architecture

• Connect the GND pin of the arduino uno board into the top/bottom slot of the breadboard.
• Connect the pin number 13 of the arduino uno board into the top/bottom slot of the breadboard.

• Connect Buzzer to Breadboard parallel to the previous connection. The connection here is vertically connected making it ideal for the source.

Step 3 : Programing

• Connect Arduino to the computer with USB .
• Open the Arduino IDE > Chose your Board Type
  

Copy the code below and paste it into your own sketch in the arduino software.

• Simple Alarm

// Simple DigitalWrite Buzzer
int buzz = 13 ; //Buzzer Kutub Positiv (+) di pin 9
void setup() {
  // put your setup code here, to run once:
  pinMode(buzz,OUTPUT);
  }
void loop() {
  // put your main code here, to run repeatedly:
  digitalWrite(buzz,HIGH);
  delay(1000);
  digitalWrite(buzz,LOW);
  delay(1000);
}

• You can test "Pirates of the Caribbean Theme Song" ( Source : GitHub )

const int buzzer = 13; //Define pin 13, can use other PWM pins  (5,6 or 9)
                       //Note pins 3 and 11 can't be used when using the tone function in Arduino Uno
const int songspeed = 1.5; //Change to 2 for a slower version of the song, the bigger the number the slower the song

• After Copy the codes, click the "Verify button" to save and compile the sketch. This will also check for any errors in the program.

• If no errors is found , now you can click "Upload button" to start installing the program into the arduino uno board.
