Umarnin Haɗawa

Don haɗa modul ɗin sarrafa motar DC L9110 guda biyu tare da Arduino, fara da haɗa fil ɗin wutar. Haɗa fil ɗin VCC akan L9110 zuwa fitowar 5V akan Arduino, kuma haɗa fil ɗin GND zuwa ɗaya daga cikin fil ɗin ƙasa na Arduino. Na gaba, don motar A, haɗa fil ɗin A1A zuwa fil ɗin dijital 2 akan Arduino da fil ɗin A1B zuwa fil ɗin dijital 3. Sa'an nan, don motar B, haɗa fil ɗin B1A zuwa fil ɗin dijital 8 da fil ɗin B1B zuwa fil ɗin dijital 9. Ka tabbata an haɗa motocin daidai zuwa fitowar su na musamman akan modul ɗin L9110.

Misalan Lamba & Bayani

A cikin aikin setup, muna buƙatar ayyana fil ɗin sarrafawa a matsayin fitarwa. Wannan yana da mahimmanci don Arduino ya sarrafa alkiblar motar yadda ya kamata:

void setup() {
  pinMode(B1A,OUTPUT);// ayyana fil a matsayin fitarwa
  pinMode(B1B,OUTPUT);
  
  pinMode(A1A,OUTPUT);
  pinMode(A1B,OUTPUT);    
  delay(3000);
}

Wannan ɓangaren lambar yana saita fil ɗin sarrafa motar, yana tabbatar da cewa Arduino na iya aika siginoni zuwa modul ɗin L9110. Babban madauki na shirin yana sarrafa motocin ta hanyar kiran ayyukan `motorA` da `motorB` tare da sigogi daban-daban don sauya alkibla:

void loop() {
  motorA('R');// Juya motar A zuwa DAMA
  delay(2000);
  motorA('L');// Juya motar A zuwa HAGU
  delay(2000);   
  motorA('O');// Kashe motar A
  delay(2000); 
  ...
}

A cikin wannan ɓangaren, ana sa motocin su juya dama da hagu, tare da jinkiri a tsakanin don lura da canje-canjen alkibla. Aikin `motorA` an ayyana shi don sarrafa motar A bisa ga alkiblar da aka shigar:

void motorA(char d) {
  if(d =='R'){
    digitalWrite(A1A,LOW);
    digitalWrite(A1B,HIGH); 
  } else if (d =='L'){
    digitalWrite(A1A,HIGH);
    digitalWrite(A1B,LOW);    
  } else {
    digitalWrite(A1A,LOW);
    digitalWrite(A1B,LOW);    
  }
}

Wannan aikin yana duba alkiblar da aka bayar kuma yana saita fil ɗin sarrafawa daidai don juya motar a alkiblar da ake so ko kashe ta.

Nuni / Abin da Za Ka Yi Tsammani

Lokacin da ka kunna lambar, ya kamata ka ga motocin suna canzawa tsakanin juyawar hagu da dama. Jinkirin yana ba ka damar lura da canje-canjen alkibla a fili. Ka kiyaye daga matsalolin gama-gari kamar haɗin da aka juya, waɗanda zasu iya haifar da hali marar tsammani ko lalacewar kayan aikin. Bugu da ƙari, ka tabbata cewa samar da wutar ka ya isa ga motocin da kake amfani da su (a cikin bidiyo a 00:00).
