Modelning Arduinoga ulanish sxemasi:

Biz RGB LED anodlarini ulaymiz & nbsp; B portining 1,2,3 satrlariga biz katodlarni minus bilan bog‘laymiz. Turli xil rang palitralarini olish uchun biz anodlarga ma'lum ketma -ketlikda PWM signalini qo‘llaymiz. Bu misolda biz maxsus PWM dasturidan foydalanamiz, garchi Atmega8 -da siz 3 ta kanal uchun PWM apparatini osongina olishingiz mumkin. PWM dasturiy ta'minoti taymerlar / hisoblagichlar etishmasligi va boshqa sabablarga ko‘ra ishlatilishi mumkin. Muayyan chastotali PWMni yaratish uchun biz 8 bitli taymer T0 to‘lg‘azish uzilishidan foydalanamiz (TIMER0_OVF_vect). Prescaler ishlatilmagani uchun taymerning to‘lib ketish chastotasi 31250Hz ga teng bo‘ladi.
Mustaqil ishlash uchun topshiriqlar:
1. Ma’ruzaning nazariy materialini o‘rganish.
2. Bundan tashqari ishlatilgan Internet -resurslarni o‘rganing.
3. Arduino sxemasida RGB ledni mustaqil o‘zingiz ulang.
4. Arduino IDEda mustaqil ravishda RGB led uchun dastur yozing.
