Ushbu kod mikrokontrollerdagi PORTB registri orqali svetofornning turli ranglari uchun yoqish va yo'qotish jarayonini amalga oshiradi. Kodning boshida yordamchi holat sozlanishi va asosiy dastur (MAIN) mavjud. DELAY nomli yordamchi funktsiya vaqtni kutilayotgan kuchli kuchga o'tish uchun ishlatiladi.
Svetofornning har bir rangi uchun kerakli pinlar yonaltiriladi va yoqiladi. Uch to'rtinchi qadam DELAYfunktsiyasi orqali kuchli kuchga o'tish uchun vaqtni kutishingiz mumkin. Ushbu kod mikrokontrollerga svetofornni yoqish, ranglarni almashtirish va yo'qotishning o'zaro mosligini amalga oshiradi. B
