4-laboratoriya ishi
Potensiometr. Arduino orqali yorug‘lik diodini yorug‘lik darajasini o‘zgartirishini namoyish etish
Ishdan maqsad: O’rnatilgan tizimlarda analog kiritish va chiqarishni dastur yordamida boshqarishni o’rganish. Analog-raqamli hamda raqamli-analog o’zgartirgich apparat va dasturiy vositalari bilan ishlashga ko’nikma hosil qilish.
Kerakli jihozlar: Arduino UNO R3, led lampalar, maket plata,potensiometr
