This is kinda far from 8052 related, but more of a electronics question.

I have a DC motor that is driven by a general purpose transistor (via an 8052 based controller). The transistor provides 12 volts output.

However, my DC motor needs less voltage. Is there a standard technique for halfing this voltage? A series resistor would do the trick but it would *waste* a TON of power...no?

Whats the best solution?

Thanks in advance
