This video shows all the steps to build the HEE-HAW Siren Project from Jaycar. The kit is based on NE555 IC. The timer NE555 IC is configured in astable mode.
You will hear a hee-haw siren similar to an ambulance and you will see the two green and red flashing LEDs.
The kit is very much similar to BuildCircuit’s project: https://www.buildcircuit.com/light-activated-police-siren-using-555-timer-and-light-dependent-resistorldr/ This kit is good for electronics beginners and extremely easy to build.
