Arduino, bluetooth si motor driver

Recommended Posts

Buna ziua!

 

Incerc sa construiesc un robotel controlat prin bluetooth  de pe telefon. Nu am cumparat shield pentru arduino, dar am cumparat un motor driver(a4990) :

Intrebarea mea este cine anume din imagine este logic power? Unde trebuie conectat? De asemenea, Vin si GND le-am conectat la Vin si GND de la modulul bt si arduino. Aici trebuie conectata si bateria de 9 V,nu?

 

Multumesc anticipat.

Logic power e tensiuna la care alimentezi si microcontrollerul cu care controlezi modulul. In cazul Arduino - 5V (borna de 5V de la Arduino, de exemplu).

Cat timp nu spui ce fel de modul bluetooth ai, nimeni nu poate spune cu exactitate cum se alimenteaza. In principiu se alimenteaza la o tensiune similara - 3.3V/5V.

Vin e tensiunea de alimentare a motoarelor. Poti alimenta Arduino la aceeasi tensiune daca folosesti mufa jack (si daca se incadreaza in specificatii: Input Voltage (recommended)7-12V)
