This video provides a comprehensive guide to building the HEE-HAW Siren Project from Jaycar. The project is centered around the NE555 timer IC, which is configured in astable mode.

Upon completion, the siren produces a distinctive “hee-haw” sound similar to an ambulance. Additionally, the project features two flashing LEDs, one green and one red, adding a visual component to the siren.

The HEE-HAW Siren Project shares similarities with a project available on BuildCircuit: BuildCircuit Project.
