o.k , my motor specification is 12 Volt-2Amp......but i'm sorry i'm not convinced about that my motors will not be able to work well because the limited current ....
i just need 12 volt signal from the opto coupler , but the current is not important at all.
this signal from the optocoupler works as a trigger for my H-Bridge circuits....but my motors draw it's volt and current from the H-Bridge Circuit.
Anyway you can look at this block diagram ...i have made it to avoid any misunderstanding and to show you my idea....may be it still a stupid one but i'm still beginner.
finally i think even if i run a motor with 5Amp it will work too because i don't draw anything from the optocoupler.
look at the block diagram and tell me if i'm still wrong or not !!
