Mi ce da Pull-up Resistor?

Takardar da Pull-up Resistor

Resistor da ake amfani da shi a cikin fagen elektroniki don taimaka da matsayin tsari na voltage na signal.

Karkashin pull-up resistor na biyu

Siffarwar karkashin aiki

A kabilu da ake gudanar da pull-up resistor, idan babban abubuwa ba a yi aiki, pull-up resistor ya "gina" yana gina input voltage signal. Idan babban abubuwa ba a gudanar, wato "high impedance" ga input. A wannan lokacin, zai iya gina voltage a input port zuwa high level ta hanyar pull-up resistor. Idan babban abubuwa ya yi aiki, zai iya bace high level da pull-up resistor ta gina. Hakan, pull-up resistor ya taimaka da pin a dogara wata siffar aiki hata idan babban abubuwa ba a gudanar.

Pull-up resistor aiki

Pull-up resistors suna sauka masu aiki da voltage states na digital circuits ta hanyar inganta voltage control idan switch ba a gudanar.
