Code logic derived from a tutorial for building a Bluetooth car using the same shield.

int enA = 6; // PWM speed for Motor A int in1 = 4; int in2 = 7;

, utilizing nearly all digital pins except for 2, 13, and the analog pins A0–A5. Output Type Control Pins Up to 4 bi-directional motors Managed via shift register Stepper Motors Up to 2 (unipolar or bipolar) Uses the same H-bridges as DC motors Servo Motors 2 hobby servos (e.g., SG90) Directly connected to Arduino pins Critical Power Management Tips

The shield is built around two L293D motor driver ICs and a to save Arduino pins.

A: Yes, but not with the AFMotor library. You will have to write your own code to directly control the shield's pins using digitalWrite() and analogWrite() .

Up to with 8-bit speed selection. Up to 2 stepper motors (unipolar or bipolar).

The shield can drive a bipolar stepper motor, making it suitable for projects like a small CNC plotter.
