Xulosa
Men bu amaliy ishni bajarish davomida Arduinoda 74HC595 shift registrini ishlatishni o’rgandim. Bu qurulma orqali juda ko’p insonlarga foyda keltiradigan buyumlar yasashni o’rgandim. Led lompochkalarini 74HC595 shift registr bilan birga ishlatganimizda turli xil buyumlar yasaymiz. Ikkinchi yasagan texnolgiyamiz ham juda qiziqarli texnolgiya ekan.Piezoelementdan foydalandik.
