mikroC: Generating Sound with PIC Microcontroller


  • Connect “+” Pin of Piezo Buzzer to Pin 8 of Arduino Uno
  • Connect “” Pin of Piezo Buzzer to Pin GND of Arduino Un0

Arduino Code

This simple code generates a tone at 4KHz

const int buzzerPin = 8; //Where your '+' of Buzzer goes to
const int frequency = 4000; //Resonant frequency of the buzzer at 4KHz

void setup() {
  pinMode(buzzerPin, OUTPUT);

void loop() {
    makeBeep(1, 1, frequency);
    makeBeep(5, 1, frequency);   
void makeBeep(int intervalSeconds, int howlongSeconds, int freq) {
  delay(intervalSeconds * 1000);
  tone(buzzerPin, freq, howlongSeconds * 1000);
