Understanding how the HW-130 maps its pins is essential, as it uses the 74HC595 shift register to handle direction controls over a serial link, freeing up crucial hardware PWM pins on your Arduino. Dedicated Hardware Pins
The HW-130 Motor Control Shield is an essential "bridge" for robotics. While it uses an older L293D architecture, its ease of use and compatibility with the Adafruit library make it the go-to choice for students and hobbyists building their first motorized creations.
Key specifications
The shield features several screw terminals along its edges to attach your motors: hw 130 motor control shield for arduino datasheet
This comprehensive technical datasheet and guide covers the specifications, pinouts, and code implementation for the HW-130 shield. Technical Specifications
Two 3-pin headers (labeled SER1, SER2) for standard hobby servos.
Located on a 2-pin terminal block. It is highly recommended to use an external supply for motors rather than the Arduino's 5V pin to avoid overheating or logic resets. Power Jumper: Jumper ON: Powers the Arduino from the motor's external power supply. Jumper OFF: Separates the logic and motor power. Remove this Understanding how the HW-130 maps its pins is
The HW-130 sits directly on top of an Arduino Uno or Mega. Because it plugs directly into the headers, certain pins are dedicated strictly to the shield's operation. Dedicated Shield Pins
Brings the Arduino reset button to the top and provides access to all six analog pins (A0-A5) for sensor integration.
To easily program the HW-130, you should use the industry-standard . This library handles the complex shift-register logic behind the scenes. Installing the Library Open the Arduino IDE. Go to Sketch -> Include Library -> Manage Libraries . Search for Adafruit Motor Shield library . It is highly recommended to use an external
connected to the Arduino's high-resolution dedicated timers for jitter-free operation. 5.imimg.com Pin Mapping & Usage
Uses a 74HC595 shift register to expand 3 Arduino pins into 8 direction control pins. Key Features & Design
The HW-130 is based on the , designed to provide bidirectional drive current for motors. Motor Driver IC: 2 x L293D
// Stop analogWrite(ENA, 0); delay(500);
