Int buttonState = digitalRead(BUTTON_PIN) // read new state In this example we will connect a Piezo buzzer to our arduino and play some basic sounds, this uses the PWM functionality of the Arduino. Switch Actuator, APEM A01 series Illuminated Push-Button Switches. PinMode(BUZZER_PIN, OUTPUT) // set arduino pin to output mode Play the Happy Birthday Song on a piezo buzzer Happy Birthday Song On Piezo Buzzer. PinMode(BUTTON_PIN, INPUT_PULLUP) // set arduino pin to input pull-up mode This library is designed for piezo buzzer to beep or play memody without using delay() function. Arduino Code – Simple Sound const int BUTTON_PIN = 7 // Arduino pin connected to button's pinĬonst int BUZZER_PIN = 3 // Arduino pin connected to Buzzer's pin Make sure that you place a copy of the pitches.h file in the same directory as the ArduinoTunes.ino sketch, or you will get a compile error from the Arduno IDE. Now copy the following code and upload it to Arduino IDE Software. Simple Arduino-Peizo-Buzzer Arduino Code Here is a link to the Arduino sketch from the demo video. Here is a simple step-by-step guide on “ How to Add Libraries in Arduino IDE“. Installing Librariesīefore you start uploading a code, download and unzip the following libraries at /Progam Files(x86)/Arduino/Libraries (default), in order to use the sensor with the Arduino board. Here is a simple step-by-step guide on “ How to install Arduino IDE“. Make connections according to the circuit diagram given below.įirst, you need to install Arduino IDE Software from its official website Arduino. If you want to stop the sound when the button is released you can use noTone(8) it is after the previous if statement.You can replace the frequency 1000 with the desired frequency in hertz, for example, 2000 for 2Khz. If the button is pressed, use the tone() function to generate a tone on the buzzer pin: In the loop() function, use the digitalRead() function to check the state of the pushbutton.Uso da função tone() irá interferir com saída PWM nos pinos 3 e 11 (em placas diferentes do Mega). Se o tom está tocando no mesmo pino, a chamada irá mudar sua frequência para a nova especificada. Se um tom já está tocando em um pino diferente, a chamada de tone () não terá efeito. In the setup() function, configure the pushbutton pin as input by adding the following line: Apenas um tom pode ser gerado de cada vez.In your Arduino sketch, configure the buzzer pin as an output by adding the following line in the setup() function:.Connect one pin to digital pin 2 and the other pin to one of the GND pins on the board. Connect the pushbutton to the Arduino board.Connect the positive terminal to digital pin 8 and the negative terminal to one of the GND pins on the board. The buzzer typically has two pins: one for the positive terminal (usually labeled “+” or “S”) and one for the negative terminal (usually labeled “-” or “N”). Connect the 5V piezoelectric buzzer to the Arduino Uno board.
