Hw 130 Motor Control Shield For Arduino Datasheet Better Patched Official

The HW-130 Motor Control Shield is not the only motor control shield available for Arduino, but it is one of the most popular and highly regarded. Here are a few key differences between the HW-130 and other popular motor control shields:

Here's a simple example of using the HW-130 shield to control two DC motors:

The HW-130 motor control shield is a popular accessory for Arduino boards that enables users to control DC motors, stepper motors, and other loads. Here's a brief overview of the shield's features and specifications:

At 1.5A per channel, the L298N gets very hot. The HW-130 includes a small aluminum heatsink (glued on). if running both motors continuously at high load. hw 130 motor control shield for arduino datasheet better

| Function | Arduino Pin | Description | | :--- | :--- | :--- | | | | | | IN1 | D4 | Direction Control A | | IN2 | D5 | Direction Control A | | Motor B Control | | | | IN3 | D6 | Direction Control B | | IN4 | D7 | Direction Control B | | Speed Control (PWM) | | | | ENA | D9 | Speed Control Motor A (Requires PWM) | | ENB | D10 | Speed Control Motor B (Requires PWM) | | Servos | | | | Servo 1 | D9 | (Shared with ENA - Check specific board revision) | | Servo 2 | D10 | (Shared with ENB - Check specific board revision) |

This means the HW-130 is designed for small to medium-sized DC motors, not for heavy-duty industrial motors. Exceeding these current limits can cause erratic behavior or damage the chip.

The (often referred to as the L293D Motor Shield) is a popular, low-cost driver for small motors. It is based on two L293D motor driver ICs and a 74HC595 shift register to minimize the number of Arduino pins used. Key Specifications The HW-130 Motor Control Shield is not the

The HW-130 shield is architected around a dual-chip H-bridge topology managed by a serial-to-parallel shift register to preserve precious microcontroller input/output (I/O) pins. L293D Based Arduino Motor Shield

Expect a ~1.5V drop between your battery and the motor.

Use the Stepper.h library with steps per revolution = 200 (common). The HW-130 includes a small aluminum heatsink (glued on)

void loop() // Forward both motors digitalWrite(in1, HIGH); digitalWrite(in2, LOW); digitalWrite(in3, HIGH); digitalWrite(in4, LOW); analogWrite(enA, 200); // Speed 0-255 analogWrite(enB, 200); delay(2000);

The (often referred to as an L293D Motor Shield ) is a popular, cost-effective solution for driving multiple DC motors, stepper motors, and servos. It is designed to stack directly onto an Arduino Uno, Mega, or Duemilanove, eliminating complex wiring for robotics projects.
