Transistor Motor Driver

Hello everyone,

I was working on a robotor project recently using about 12 DC motors (6-12V) controlled by an Arduino. However, i decided to try to build a motor driver using bipolar transistors. The driver should be able to power each of the 12 motors in both directions with 2 and not more batteries at all. So I came to the following circuit:

Tinkering with Wolfram Alpha

Well, this are fine news for people tinkering with stuff. The still new search-engine Wolram Alpha will make any kind of reference book obsolete. The now also translate resistor codes. (repost form Eggshell Robotics)
