Just picked up an HW-130 Motor Control Shield for an upcoming robotics project. It’s a great, cheap shield for driving two DC motors (or one stepper) based on the L298P driver.
#include <Stepper.h> // HW 130: Stepper coils on M3 & M4 (Pins D8,D9,D10,D11) Stepper myStepper(2048, 8, 10, 9, 11); // steps per rev, pins hw 130 motor control shield for arduino datasheet free
The HW-130 Motor Control Shield is a stackable shield designed for Arduino Uno, Arduino Mega, and other compatible boards. It provides a convenient and efficient way to control DC motors, stepper motors, and other high-power devices. The shield features a range of components, including: Just picked up an HW-130 Motor Control Shield
