Микроконтроллерная плата Raspberry Pi Pico является отличной отправной точкой для новичков в мир электронике. И в данном материале мы расскажем про проект организации последовательностей включения светодиодов типа «бегущие огни» на основе Raspberry Pi Pico.
В данном проекте мы реализуем создадите селектор последовательностей включения светодиодов на основе Raspberry Pi Pico. Помимо микроконтроллерной платы здесь будет десять светодиодов и четыре кнопки. Для каждой кнопки будет своя последовательность светодиодов.
Распиновка платы Raspberry Pi Pico:
Схема подключения компонентов:
Код программы для Raspberry Pi Pico следующий:
