xulosa

Biz bu laboratoriya mashg’ulotini bajarish davomida 8x8 matritsaning qanday tuzilganligi va u orqali turli tasvirlar hosil qilish mumkinligini o’rgandik. O’rgangan bilimlarimizni boshqa o’lchamdagi matritsalar orqali katta tasvirlarni yaratishda katta matritsalardan qanday foydalanishni bilib oldik.

Laboratoriya ishini bajarish

1. Quyidagi sxemani yeg’ing

DC stepper motor (Шаговый двигатель) +5v da ishlovchi ammo tezligi kam bo’lgan qurilma xisoblanadi.

Unda jami 5 ta oyoq bo’lib ularni mikro sxema oraqali yoki ULN2003 Driver Board tayyor DC stepper motor controller yordamida boshqariladi. Unda bir GND, VCC va 3ta analogik kanali mavjud.
