Code Explanation of Arduino Interface Buzzer
Initializing Variables:
int speakerPin = 12;
int numTones = 10;
int tones[] = {261, 277, 294, 311, 330, 349, 370, 392, 415, 440};
numTones: Represents the number of tones in the array.tones[]: An array containing frequencies for 10 different tones. These frequencies correspond to musical notes from mid C to A.
Setup Function:
void setup() {
for (int i = 0; i < numTones; i++) {
tone(speakerPin, tones[i]);
delay(500);
}
noTone(speakerPin);
}
- The
setup()function runs once when the Arduino is powered on or reset. - It iterates through the
tones[]array, playing each tone for 500 milliseconds (0.5 seconds) using thetone()function. - After playing all tones,
noTone()function is called to turn off the tone generation on the speaker.
Loop Function:
void loop() {
// This function is empty as we don't need any continuous operation in this code.
}
- The
loop()function runs continuously after thesetup()function completes. - In this case, the
loop()function is empty because there’s no need for continuous operations. The tones are played in thesetup()function.
