⭐️BJT level crossing lights⭐️

The first U.S. level crossing gate was in operation from August 27, 1867. It was only in early 1900 that lights were introduced. The LED’s added at the top is merely a customisation which is usually absent on traditional level crossing lights. ** For your safety, when approaching a level crossing and you see the red lights flashing, be warned that a train is approaching. Remember you should stop. Not only is it unlawful to cross the train tracks while the red lights are flashing but it also could prove to be fatal if you ignore the red flashing lights and decide to cross the tracks. ** Valid arguments can be made about the number of components used in this circuit. Arguments could also be made about logic gate propagation settings or simulator settings but what must be realised is that this is a fun circuit not intended for commercialisation. If anyone feels like making positive contributions in terms of circuit improvements, feel free to make those recommendations along with a link to a circuit in which those recommendations have been implemented. Such collaboration will be appreciated by the entire EC community. Have a great day everyone.
