Police Lightbar Sim On Arduino


One of my long time dreams, as silly as this is, was to have a police car with working lightbar on my model railroad layout. Now, there are plenty of ‘flasher’ circuits out there, but I have yet to find one that’s worth the money.

On one of the many deployments I had in the Navy, I took advantage of the free time and technical resources and really beefed up my working knowledge of solid state electronics. Being underway on a submarine means no internet connectivity, so I had no way to research common ‘beginner’ circuits and ICs. This led me to build massive logic ciruits of out the basic building blocks: AND, NAND, OR, NOR, XOR and NOT gates.
