Kodin Arduino da Bidiyo: L293D Mai Sarrafa Motar DC (ba tare da sarrafa saurin ba)

Wannan koyarwar ta shafi yadda ake amfani da mai sarrafa motar L293D tare da Arduino don sarrafa motar DC. L293D yana ba ka damar juya motar a duka alkiblar agogo da kuma alkiblar agogo baya. Ta bin wannan jagorar, za ka koyi yadda ake haɗa kayan aiki da kuma tsara Arduino don cimma sarrafa motar da ake so.

A cikin wannan aikin, za mu yi amfani da direban motar L293D don sarrafa motar DC guda ɗaya. Motar za ta iya canza alkibla bisa ga umarnin da aka bayar a cikin lambar Arduino. Don ƙarin fahimtar saitin da lambar, yana da amfani a kalli bidiyon da ke da alaƙa (a cikin bidiyo a 00:00).

Bayanin Kayan Aiki

L293D wani haɗaɗɗen kewayawa ne da aka ƙera don sarrafa motoci. Yana iya sarrafa motocin DC guda biyu a lokaci ɗaya ko kuma motar stepper guda ɗaya. Chip ɗin yana amfani da tsarin H-bridge don ba da damar sarrafa alkibla ta hanyar canza polarity na wutar lantarki da ake amfani da ita ga motar. Wannan sassauci ya sa ya zama zaɓi mai kyau don ayyukan robotics da automation.

Baya ga L293D, za mu yi amfani da allon Arduino don aika siginonin sarrafawa zuwa direban motar. Arduino zai samar da matakan dabaru da ake buƙata don kunna motar da kuma tantance alkiblar juyawarta. Saitin kuma zai buƙaci motar DC da kuma tushen wutar lantarki da ya dace da buƙatun wutar lantarki na motar.

Don haɗa mai sarrafa motar L293D zuwa Arduino, fara da haɗa wutar da ƙasa. Haɗa pin 4 da pin 5 na L293D zuwa ƙasa. Sa'an nan, haɗa pin 1 (Vcc1) zuwa fitowar 5 V na Arduino. Don Vcc2 (pin 8), haɗa shi zuwa tushen wutar lantarki na waje, tabbatar da cewa ya dace da ƙayyadaddun wutar motar.

Na gaba, haɗa pin ɗin kunna (pin 1) zuwa pin 8 akan Arduino don sarrafa wutar motar. Don shigarwar sarrafa motar, haɗa pin 2 (1A) na L293D zuwa pin 2 akan Arduino da pin 7 (2A) zuwa pin 7 akan Arduino. A ƙarshe, haɗa tashoshin motar zuwa pin 3 (1Y) da pin 6 (2Y) akan L293D.
