Hw 130 Motor Control Shield For Arduino Datasheet Free Fix Here

The shield uses two L293D motor driver ICs and one 74HC595 shift register to expand the Arduino's control pins. :

void loop() // Forward at half speed using PWM analogWrite(MOTOR_A_IA, 128); // 50% duty cycle digitalWrite(MOTOR_A_IB, LOW); delay(2000);

Some versions of the HW‑130 have a jumper labeled or 5V‑EN . If this jumper is in place, the motor power supply also feeds the Arduino’s 5 V rail. Remove this jumper unless you are absolutely certain that your motor supply voltage is within a safe range for the Arduino (typically 7 V–12 V). A 12 V supply may be acceptable, but a 15 V supply can damage the Arduino.

The HW‑130 is a popular clone of the original . Because the original Adafruit design has been discontinued, the HW‑130 often serves as a low‑cost alternative that maintains full pin and code compatibility. The shield acts as a bridge between the low‑current logic pins of the Arduino and the high‑current demands of various motors. It also uses a 74HC595 serial‑to‑parallel converter to reduce the number of Arduino pins required, leaving more digital and analog pins free for other sensors and components. hw 130 motor control shield for arduino datasheet free
