Multiple Choice
Bluetooth orqali ‘1’ yuborilganda motor aylanmayapti, lekin LED yonmoqda. Muammo nimada bo‘lishi mumkin?
RX va TX pinlari joyi almashtirilgan
Motor yonib ketgan
L298N quvvatlanmagan
a va c javoblar to‘g‘ri
14
Multiple Choice
Agar HC-05 moduli VCC 3.3V piniga ulanib ishlamay qolsa, sabab nima bo‘lishi mumkin?
Modul faqat 3.3V da ishlaydi
Modul 5V da ishlaydi
Modul USB orqali quvvat oladi
RX/TX ulanishida xato bor
15
Multiple Choice
L298N dagi ENA pin qaysi vazifani bajaradi?
Motor yo‘nalishini o‘zgartiradi
Motor tezligini PWM orqali boshqaradi
Bluetooth signallarini uzatadi
Quvvatni yoqadi
16
Multiple Choice
Quyidagi kodda motor juda tez aylanmoqda. Tezligini kamaytirish uchun qaysi qatorda o‘zgartirish kiritish kerak?
analogWrite(ENA, 255);
analogWrite(ENA, 0);
digitalWrite(ENA, LOW);
analogWrite(ENA, 100);
analogWhite(INA, 55);
17
Multiple Choice
L298N modulida motor bir tomonga aylanmoqda, orqaga aylanmayapti. Sababi:
IN1 va IN2 pinlar noto‘g‘ri ulangan
ENA pin uzilgan
Motor yomon
Bluetooth signali kuchsiz
18
Multiple Choice
Agar motor Bluetooth orqali “1” yuborilganda sekin aylanayotgan bo‘lsa, eng to‘g‘ri sabab nima bo‘lishi mumkin?
ENA pin kodda analogWrite(ENA, 100); deb yozilgan
IN1 va IN2 pinlar joyi almashgan
TX va RX joyi xato
Arduino kuchli signal yubormayapti
19
Multiple Choice
Quyidagi kodda motor umuman ishlamayapti:
if (data = '1') {
digitalWrite(IN1, HIGH);
digitalWrite(IN2, LOW);
} Nima sababli?
Motor kuchsiz
IN1 pin noto‘g‘ri
ENA pin uzilgan
Tenglik belgisi xato qo‘yilgan (== bo‘lishi kerak)
20
Multiple Choice
Quyidagi kodda Serial.begin(9600); o‘rniga Serial.begin(115200); yozilsa nima bo‘ladi?
Hech narsa o‘zgarmaydi
Motor sekin aylanadi
Bluetooth aloqa ishlamay qoladi
Kod tezroq ishlaydi
