Ambulance siren project Kit

Description

This is the ambulance siren kit that help you to make Ambulance siren project. This is a wailing siren so when you press the button it goes on at full volume and slows down with time. These kinds of sirens are used for making alert systems. You can change the values of the resistors and capacitors that we used in this project but don’t change the connections of the IC and transistors.

Connect a 5 volts supply to the positive and negative rails of the breadboard. We are using Bc547 and BC557 transistors which provide accurate current and power to the circuit. There is a push button, and you can press it to ring the buzzer. You can also check out our project. There is all the components available in this kit with user manual which will help you to built this project.
