PROJECT DESCRIPTION

Police Siren

A siren is a loud and typical sound making device. It is used to alert the persons and to attract the moment various vehicles mounted with sirens used for example VIP’s,.and in Vehicles such as ambulances, police cars and fire trucks.

This circuit is used to generate a police siren sound using Simple 555 timers and a speaker.The frequency of this siren is around 1KHz,To achieve this frequency generation two 555 timers one in monostable mode and the other one is in astable mode..A speaker of 8 ohm and halfwatt is used to deliver the siren sound.An adjustable knob is used to set the frequency or match the sound in similar to police siren.

Note: This DIY kit doesn't include soldering iron, multimeter, cutter and screwdriver as it is not required.

One solderless multipurpose breadboard and set of basic components will be provided for each of the 5-in-1 Solderless project kit. This 5-in-1 Solderless Project kit will be provided with additional 4 free circuits which can be built by additionally procuring very few components. Thus, students can explore and develop total 5 projects at the cost of 1 project kit only.

All the engineering, diploma and other technical students from first year to final year can get hands on experience in designing and developing various electronics projects with these 5-in-1 solder less project kits. Completely assembled project is available in image format besides real time working in audio visuals to help students to complete one DIY kit with ease and then try engineering skills to attempt the other free circuits provided as no additional components are required. With this solderless breadboard approach none of the component is soldered, hence all the components can be used again and again to try such multiple circuits.

Note1: All the 5 project circuits are tested and working.
