Arduino Datasheet Free - Hw 130 Motor Control Shield For

Here is the simplest sketch to test Motor 1 on channel A (Pins D4, D5):

// HW 130 Motor Control Shield - Free Datasheet Example
// Motor 1: Speed = D5 (PWM), Direction = D4
#define MOTOR1_DIR 4
#define MOTOR1_PWM 5
void setup() 
pinMode(MOTOR1_DIR, OUTPUT);
pinMode(MOTOR1_PWM, OUTPUT);
Serial.begin(9600);
Serial.println("HW 130 Test Ready");

void loop() 
// Forward at 70% speed
digitalWrite(MOTOR1_DIR, HIGH);
analogWrite(MOTOR1_PWM, 179);  // 179 = ~70% of 255
delay(2000);
// Stop (coast)
digitalWrite(MOTOR1_PWM, LOW);
delay(1000);
// Reverse at full speed
digitalWrite(MOTOR1_DIR, LOW);
analogWrite(MOTOR1_PWM, 255);
delay(2000);
// Brake (set both PWM and direction to LOW)
digitalWrite(MOTOR1_DIR, LOW);
digitalWrite(MOTOR1_PWM, LOW);
delay(2000);

For stepper motors (using standard Stepper library):

#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
void setup() 
myStepper.setSpeed(12);  // 12 RPM
myStepper.step(2048);    // one full rotation

Here is a free, ready-to-use code snippet to test the HW-130 shield. This code will accelerate Motor A forward, then reverse, and stop.

// HW-130 Motor Shield Pin Definitions
#define M1_SPEED 3  // PWM Pin for Motor A Speed
#define M1_DIR  12  // Direction Pin for Motor A
#define M2_SPEED 11 // PWM Pin for Motor B Speed
#define M2_DIR  13  // Direction Pin for Motor B
void setup() 
// Configure pins as outputs
pinMode(M1_SPEED, OUTPUT);
pinMode(M1_DIR, OUTPUT); Here is the simplest sketch to test Motor
// Optional: If your board uses Brake pins (D8/D9)
// pinMode(9, OUTPUT); digitalWrite(9, HIGH); // Disable Brake M1

void loop() 
// --- Motor A Forward Acceleration ---
digitalWrite(M1_DIR, HIGH); // Set Direction Forward
// Accelerate from 0 to full speed
for (int speed = 0; speed <= 255; speed++) 
analogWrite(M1_SPEED, speed);
delay(20);

delay(1000); // Run at full speed for 1 second
// --- Stop ---
analogWrite(M1_SPEED, 0);
delay(1000);
// --- Motor A Reverse ---
digitalWrite(M1_DIR, LOW); // Set Direction Reverse void loop() // Forward at 70% speed digitalWrite(MOTOR1_DIR,
// Run at half speed
analogWrite(M1_SPEED, 128);
delay(2000);
// Stop
analogWrite(M1_SPEED, 0);
delay(2000);

The HW-130 is a low-cost, dual H-bridge motor driver shield compatible with Arduino Uno, Leonardo, and Mega. It lets you control two DC motors (speed + direction) or one stepper motor independently.

| IN1 | IN2 | ENA (PWM) | Motor A State | |-----|-----|-----------|----------------| | LOW | LOW | x | Brake (free stop) | | HIGH| LOW | 0–255 | Forward speed | | LOW | HIGH| 0–255 | Reverse speed | | HIGH| HIGH| x | Brake (short stop) |
