Hw 130 Motor Control Shield For Arduino Datasheet -

#include <AFMotor.h> AF_Stepper stepper(48, 1); // 48 steps per revolution, motor port 1 (M1+M2)

void setup() motor1.setSpeed(150); // 0-255 motor2.setSpeed(200); motor1.run(FORWARD); motor2.run(BACKWARD); hw 130 motor control shield for arduino datasheet

void setup() stepper.setSpeed(30); // 30 rpm #include &lt;AFMotor

void loop() motor1.run(FORWARD); motor2.run(BACKWARD); delay(2000); motor1.run(RELEASE); // stop motor2.run(RELEASE); delay(1000); Comparison with Other Shields | Feature | HW-130

#include <AFMotor.h> AF_DCMotor motor1(1); // M1 AF_DCMotor motor2(3); // M3

| Issue | Likely Cause | Solution | |----------------------------|-----------------------------------------------|-------------------------------------------| | Motors not spinning | Insufficient voltage/current | Use external 7.2–9V supply | | IC gets very hot | Current >600 mA per channel sustained | Reduce load, add heatsink, or use relays | | Erratic motor movement | Glitching due to inductive kickback | Add 100nF caps across motor terminals | | Stepper motor skips steps | Too high speed or low current | Reduce speed, increase voltage | | Shield interferes with SPI | Pins 11–13 are used partially (13 free) | Avoid SPI devices unless remapped | Note: The L293D has a dropout voltage of ~1.5V. For a 6V motor, supply at least 7.5V. 9. Comparison with Other Shields | Feature | HW-130 (L293D) | L298N Shield | TB6612 Shield | |-----------------------|------------------------|--------------------|---------------------| | Max current | 0.6A continuous | 2A | 1.2A | | Voltage range | 4.5–12V | 5–24V | 4.5–13.5V | | PWM frequency noise | Audible (~1kHz) | Lower | Ultrasonic (high) | | Efficiency | Poor (linear-like) | Moderate | Good | | Price | Very low (~$5) | Low (~$8) | Moderate (~$12) |
