![]() Industrial Safety: This circuit can be used in industrial settings to signal an emergency or to warn workers of unsafe conditions.Security Systems: The siren and LED in this circuit can be used in security systems to alert people of potential threats or danger.Emergency Vehicles: This circuit can be used in emergency vehicles like ambulances, police cars, and fire trucks to alert other drivers and pedestrians.You can also adjust the delay time to change the speed of the siren effect. The higher the value, the higher the pitch of the siren sound. You can customize the siren sound by changing the value passed to the tone() function. The loop will continue indefinitely, creating the siren effect. The code above will turn on the LED and play the siren sound through the buzzer for 0.1 second, then turn off the LED and stop the siren sound for another 0.1 second. then with a frequency of 500 repetitions per secondĭigitalWrite(7, LOW) // turn off the soundĭelay(1) // wait 1 millisecond and restart from the for statement (350 repetitions)ĭelay(50) // wait 50 milliseconds before playing the second round of soundsįor (i = 0 i < 150 i++) // define the duration of the second sound (150 cycles of 4 milliseconds)ĭigitalWrite(4, LOW) // turn off the ledĭelay(2) // wait 2 milliseconds (repeat sound every 4 milliseconds and thenĭelay(2) // wait 2 milliseconds and loop 150 times It actually repeats the sound every 2 milliseconds e ![]() The extended description of the use of the for statement is availableĭigitalWrite(7, HIGH) // turn on the soundĭigitalWrite(4, HIGH) // turn on the ledĭelay(1) // wait 1 millisecond.

These lights can be programmed to blink in a specific pattern, similar to the ones used by emergency vehicles. In addition to the siren sound, the project can also include flashing lights using LED lights or other components. The sound can be programmed to produce different tones and frequencies, which can be adjusted to create a siren sound that is similar to that of an ambulance. To create the siren sound, the project uses a piezoelectric buzzer or a speaker, which is controlled by Arduino. This project is a great way to learn about programming and electronics, and it can be easily customized to create different types of sounds. An Arduino Ambulance Siren Alarm is a project that involves using an Arduino microcontroller and a few electronic components to create a siren sound similar to the ones used by emergency vehicles such as ambulances.
