Yes, two AA batteries at 1.5v each would equal only 3 volts when connected in series. The Arduino needs 5v so [AI] decided to use a MAX756 DC-to-DC step-up regulator to maintain a steady stream of 5v.

The project is simply about controlling the direction of two DC motors with simple digital signals by using L293D with Arduino. The L293D is an H-bridge motor driver integrated circuit used to control ...
