Because it uses a shift register, most motor control signals are handled internally. However, certain Arduino pins are "reserved" when the shield is plugged in. Arduino Pins Used Description 4, 7, 8, 12 Communicates with the 74HC595 latch. PWM Speed (DC) 3, 5, 6, 11 Controls motor speed via PWM. Servo 1 Digital Pin 9 Connects to the standard Servo 1 header. Servo 2 Digital Pin 10 Connects to the standard Servo 2 header. Analog Inputs Generally free for sensors or extra I/O. 3.
