Code ya Arduino mpe Video: Contrôleur ya moteur DC L293D (ezali na contrôle ya vitesse te)

Lithu eye ya kolandela ndenge ya kosalela contrôleur ya moteur L293D na Arduino mpo na kokamba moteur ya courant continu. L293D e pesaka yo nzela ya kopelusa moteur na ngambo mibale: na ngonga ya ngonga mpe na ngonga ya ngonga. Na kolanda malako oyo, okoyekola ndenge ya kosala câblage ya ba composants mpe ya kosala programme ya Arduino mpo na kozwa contrôle ya moteur oyo olingi.

Na projet oyo, tokosalela driver ya moteur L293D mpo na kokamba moteur moko ya courant continu. Moteur akokoka kobongola direction kolanda ba commandes oyo ekomami na code ya Arduino. Mpo na kososola malamu mise en place mpe code, ezali malamu kotala vidéo oyo elandi (na vidéo na 00:00).

Matériel oyo esengeli

L293D ezali circuit intégré oyo esalelami mpo na kokamba ba moteurs. Ekoki kokamba ba moteurs mibale ya courant continu na mbala moko to moteur moko ya stepper. Chip oyo esalelaka configuration ya H-bridge mpo na kopesa nzela ya contrôle ya direction na kobongola polarité ya tension oyo epesameli moteur. Flexibilité oyo esalaka ete ezali choix ya malamu mpo na ba projets ya robotique mpe automatisation.

Na libanda ya L293D, tokosalela carte Arduino mpo na kotinda ba signaux ya contrôle na driver ya moteur. Arduino ekobimisa ba niveaux ya logique oyo esengeli mpo na kopesa nzela na moteur mpe koyeba direction ya libale na yango. Mise en place ekosenga mpe moteur ya courant continu mpe source ya courant oyo ekokani na ba exigences ya tension ya moteur.

Instructions ya Câblage

Arduino wiring for L293D motor driver with battery

Arduino wiring for L293D motor driver

Mpo na kosala câblage ya contrôleur ya moteur L293D na Arduino, banda na kosangisa courant mpe ground. Singa pin 4 mpe pin 5 ya L293D na ground. Na nsima, singa pin 1 (Vcc1) na sortie 5 V ya Arduino. Mpo na Vcc2 (pin 8), singa yango na source ya courant ya libanda, mpe kotala ete ekokani na spécification ya tension ya moteur.

Na nsima, singa pin ya enable (pin 1) na pin 8 ya Arduino mpo na kokamba courant ya moteur. Mpo na ba entrées ya contrôle ya moteur, singa pin 2 (1A) ya L293D na pin 2 ya Arduino mpe pin 7 (2A) na pin 7 ya Arduino. Na suka, singa ba terminaux ya moteur na pin 3 (1Y) mpe pin 6 (2Y) ya L293D.

Ba Exemples ya Code & Explication

Code oyo elandi ebandisaka ba pins mpe esalaka mise en place ya contrôle ya moteur. Ba identifiants oyo esalelami ezali P1A mpo na pin ya liboso ya contrôle ya moteur mpe EN12 mpo na pin ya enable. Fonction ya setup esalaka ba pins lokola ba sorties.

void setup() {
  Serial.begin(9600); // mise en place ya Serial Monitor mpo na kolakisa information
  pinMode(P1A, OUTPUT); // définir pin lokola OUTPUT mpo na P1A
  pinMode(P2A, OUTPUT); // définir pin lokola OUTPUT mpo na P2A
  pinMode(EN12, OUTPUT); // définir pin lokola OUTPUT mpo na 1,2EN enable
}

Na boucle, moteur epesameli commande ya kopelusa na ba directions mibale na ba délais na kati. État ya moteur ekomami na moniteur ya série na kosalela Serial.println.

void loop() {
  Serial.println("Kopelusa CW");
  digitalWrite(EN12, HIGH); // Enable 1A mpe 2A 
  digitalWrite(P1A, HIGH); // kotinda signal HIGH na P1A
  digitalWrite(P2A, LOW); // kotinda signal LOW na P2A
  delay(3000); // moteur ezali kotambola mpo na secondes 3
  digitalWrite(EN12, LOW); // Disable 1A mpe 2A
}

Extrait oyo elakisi ndenge ya kokamba direction ya libale ya moteur na kobongola ba niveaux ya logique oyo batindami na P1A mpe P2A. Moteur ezali kotambola mpo na secondes 3 liboso ya kotelema mpe kobongola direction.

Tala ndenge ba drivers ya demi-pont ya L293D basalelami:

L293D lokola demi-pont CW — L293D lokola demi-pont CW

L293D lokola demi-pont CCW

L293D lokola demi-pont CCW — L293D lokola demi-pont CW

L293D lokola demi-pont CCW

Démonstration / Nini Okoki Kozela

Ntango setup esili mpe code ekomi kotomelama, osengeli komona moteur ezali kopota na direction moko na secondes 3, kozonga na secondes 2, mpe na sima kopota na direction oyo ekeseni na secondes 3 mosusu. Eteni ya moteur ekomama na écran ya serial monitor, mpo na kondima ba actions (na vidéo na 12:00).

Makambo ya mbeba oyo ezali mingi ezali kotalela ete tension ya malamu epesamela moteur mpe kotalela ete ba connexions ya moteur ezali malamu. Soki moteur eyambi te, tala lisusu ba câbles mpe ba connexions ya courant.
