I just realized that getting 1200 milliamps running two motors
bi-directionally is equivalent to running four motors
uni-directionally at 2400 from a total power dissipation standpoint.
I.e., there are still 600 milliamps running through each driver.

| (...) You mean running FOUR motors uni-directionally from ONE L293D chip, right? ...and TWO motors bi-directionally from ONE L293D chip? (29 years ago, 28-Mar-96, to lugnet.robotics.handyboard)
