| Dual Stepper Motor Control (Arduino UNO R3) | |
| Controls the speed and direction of two stepper motors | |
| via two analog inputs. Used to achieve two-dimensional | |
| movement controlled by a joystick. End-of-track sensors | |
| prevent damage to the structure and motors. | |
| Based on "Speed Control" example of the Stepper lib. | |
| Please note the Stepper library produces a bipolar sequence. | |
| By swapping the two middle cables, a unipolar seq. is obtained. |
