Police Car LED effect Using IC555
PCBway: only $5 for 10 pcbs from https://www.pcbway.com/?from=CZcouple
My 5-year old son asked me to create a Police Car like flashing light that he can put on top of his nerf-gun, while playing around with his mates. No worries mate, sounds like a plan to me. Bang, weekend sorted.
In this tutorial I am going to create a Police Light themed LED Flashing circuit using the 555 timer IC. This circuit alternatively flashes between the Red and the Blue LED's while blinking each of them individually similar to the police strobe lights. To add some spice to this project you can also add a police siren to this circuit. However, I just wanted to keep it simple.
Watch this video for detailed step by step instructions on how to build this circuit and for a complete instruction on how the circuit works.
