Hw 130 Motor Control Shield For Arduino Datasheet Better -

Use the screw terminals:

// Motor A #define ENA 6 // (if jumper removed) or set to 255 if hard-wired #define IN1 12 #define IN2 13

This article serves as the to the raw datasheet. We will dissect every technical specification, explain the actual circuit logic, provide corrected wiring diagrams, and show you how to maximize performance. By the end, you will know more about the HW-130 than any six-page datasheet could ever teach you. hw 130 motor control shield for arduino datasheet better

// Map IN1,IN2,IN3,IN4 accordingly

While the HW-130 board simplifies the process, its heart is the L293D chip. Knowing its capabilities is key to understanding the shield's limitations: Use the screw terminals: // Motor A #define

Designed for Arduino Uno, Mega, and Duemilanove. Capacity & Connections The shield can simultaneously control:

: Pull-down resistors ensure motors stay disabled during Arduino power-up to prevent erratic movement. 5.imimg.com Pinout and Control Logic // Map IN1,IN2,IN3,IN4 accordingly While the HW-130 board

In general, the shield uses the following Arduino pins internally (you don't need to wire these manually!):

Since the shield uses a shift register to control motor direction, it frees up several Arduino pins for other uses. Arduino Pin(s) Used Connected to Timer1 for jitter-free control. Connected to Timer1. DC/Steppers Pins 4, 7, 8, 12 Used by the 74HC595 shift register. Pins 3, 5, 6, 11 Direct PWM control for motor speed. Unused Pins Digital 2, 13; Analog A0–A5 Available for sensors or other modules. Power Management & Jumpers
