Подскажите, пожалуйста. Собрал замок тук-тук, который по определенному стуку открывает дверь. Так вот после введеной последовательности обесточиваю плату, последовательность не сохраняется и приходится вводить ее заново. Тут код программы: http://m.instructables.com/id/Secret-Knock-Detecting-Door-Lock/

А в EEPROM записать?
