Hw 130 Motor Control Shield For Arduino Datasheet Better [updated] Direct
HW-130 Motor Control Shield is a popular, low-cost "plug-and-play" driver based on the classic
// Stop analogWrite(enA, 0); analogWrite(enB, 0); delay(1000); hw 130 motor control shield for arduino datasheet better
- “Motor only runs in one direction” → check if both IN pins toggle.
- “Shield gets very hot” → verify PWM frequency below 25 kHz and add external flyback diodes.
- “Arduino resets when motor starts” → add bulk capacitor and separate logic/motor grounds.

void setup() pinMode(dir1, OUTPUT); pinMode(pwm1, OUTPUT); digitalWrite(dir1, LOW); void loop() // Motor A forward digitalWrite(motorAPin1, HIGH); digitalWrite(motorAPin2, LOW);- VIN (motor supply): 6–12V DC connected to screw terminal. Use appropriate gauge wire.
- GND: Common ground; connect Arduino GND and motor supply GND together.
- Arduino 5V: Logic supply from Arduino; do not supply external 5V to shield unless intentional.
The HW-130 Motor Control Shield is a compact and lightweight shield that can be easily mounted on top of an Arduino board. It is designed to provide a simple and intuitive way to control motors and other loads, making it an ideal solution for a wide range of applications, including robotics, automation, and IoT projects. “Motor only runs in one direction” → check
