LED Control with ATmega
Worked for 1 min 46 sec
Asosiy arxitekturani tanladim: 12 V kirish 20 A gacha, LEDlar alohida past-tomon N-MOSFETlar bilan boshqariladi, ATmega 5 V buck regulyatordan quvvat oladi. Terminal bloklar kuchli tok uchun through-hole bo‘ladi; qolgan elektronika SMD.

Kredit tugagani uchun davom ettira olmadim, lekin sxema asosiy qismi tayyorlandi.
Bajarildi:
- Loyiha nomi yangilandi: 10-Channel LED Strip Controller
- Talablar Project Specification fayliga yozildi.
- ATmega328P-AU, 12V→5V buck regulyator, 10 ta N-MOSFET, 10 ta LED chiqish terminali, 12V kirish, knopka va AVR ISP header qo‘shildi.
- 10 ta kanal 12V LED lenta uchun low-side MOSFET sxemasi ulandi.
- Har kanalga gate rezistor va gate pull-down qo‘yildi.
- ATmega quvvat pinlari, AVCC, AREF decoupling, RESET pull-up, ISP, knopka ulandi.
- 12V_IN va LED kanallari tok qiymatlari bilan belgilandi: 12V_IN = 20A, har LED_CH = 2A.
- Electrical Rule Check’da ERROR/WARNING chiqmadi.
- Design Rule Check’da airwire xatolari bor, bu normal: PCB hali joylashtirilmagan/routing qilinmagan.
Qolgan ishlar:
- Firmware starter faylini yaratish.
- Board bring-up/test plan faylini yaratish.
- Siz sxemani tasdiqlagandan keyin PCB bosqichi: board o‘lchami, joylashtirish, kuchli tok yo‘llari uchun layout rules, routing va DRC tozalash.
