int currentPin = A0; float voltage, current; hw 130 motor control shield for arduino datasheet
The is a popular, low-cost motor driver shield designed for Arduino Uno, Arduino Leonardo, and similar compatible boards. It is based on the L293D quadruple half-H driver IC, making it ideal for driving small DC motors, bipolar stepper motors, and even solenoids. This shield is a clone or derivative of the well-known Adafruit Motor Shield V1 design, and it offers an entry-level solution for robotics and mechatronics projects.
