Laboratoriya №7
Laboratoriya ishining maqsadi: Potentsiometrni turli loyihalarda ishlatishni o‘rganing.
Potentsiometr - bu kichik komponent, uni qanday ishlatishni bilishingiz kerak.
U ko‘pincha musiqiy asboblar hajmini boshqarish, chiroqlar yorqinligini boshqarish va boshqalar kabi sxemalarda ishlatiladi.
Potentsiometr - sozlanishi qarshilikka ega o‘zgaruvchan qarshilik. Potentsiometrlar robototexnika sohasida har xil parametrlarni - ovoz balandligi, quvvat, kuchlanish va boshqalarni boshqaruvchi sifatida ishlatiladi. Bizning modelimizda LEDning yorqinligi potansiometr tugmasining aylanishiga bog‘liq bo‘ladi. Bu ham asosiy sxemalardan biridir.

Serial.print("\t output = ");
Serial.println(outputValue);

// keyin o'rnatish uchun analog-raqamli konvertor
// oxirgi o'qish:
delay(2); // 2 millisekund kuting(s)
