Siren generation is an interesting task for electronic beginners. Sirens are very important in our daily life for giving signals and warnings. Many ICs are available in markets to make our favorite sirens. A simple IC which helps us to make four sirens is UM3561. By using two select inputs, we can generate four sirens. They are police siren, ambulance siren, fire engine siren and machine gun sound. We had already seen the circuit to generate sirens using UM3561 in my previous blog. Here, we will see the video demonstration of the same.
