Code of this little project is also very simple so that you can tinker the sketch without too much difficulty. . This powerful audio-visual alert device is realized using the renowned Arduino platform. Now it is very easy to build your own siren sound alarm, small enough to be carried in a garment pocket. How Sync Works tone uses one of the builtin timer on the Arduino and that timer operates independently of the delay. You can change the siren sound e.

In order to generate a wailing sound, two for loop are used in the program to modulate the frequency; one for loop for to increment from lower to a higher frequency and another one for loop to decrement from higher to a lower frequency. If you want a video tutorial on this, check this out: Let us take three as an example to understand it. If you are ready to construct this project on a veroboard, it is easy to operate from any 12V automobile battery. The conditional if-else is used after to switch between different functions. The sound effect of the siren can be modified by varying the frequency range, the time delay, also by additional modulation of frequency and time contents.

Connect the Piezo buzzer with a 100 ohm resistor to the negative rail and positive end of buzzer connected to pin 13. The 9V battery powered circuit produces a loud, wailing sound as a warning signal. Connect 5V with another button pin as shown in the circuit diagram. Or in other words, we can say that if you want to play district beats, you should check the difference between the delay time and duration of tone as both these functions are working parallel. For more details about this, go to article. Since we are using a button press to switch between the tones, we have to remove the problem of button debouncing, which I removed by software implemention using a boolean Debounce function.
