This section provides a simple walkthrough for setting up the Go to product viewer dialog for this item. to control two DC motors. Required Components Arduino UNO R3 or equivalent. HW-130 Motor Control Shield. DC Motors. External Power Supply ( 7.4V7.4 cap V Battery Pack). Step-by-Step Setup
offers flexible power options. You can choose to power the motors and the Arduino from a single source, or separate them to protect the Arduino. Connect your external battery ( 12V12 cap V recommended).
Avoid this method if your motors draw more than 500mA. High current draws can cause voltage drops that reset the Arduino. Option B: Isolated Power Supply (Recommended) Setup: Remove the PWR Jumper completely from the shield.
Powering the HW‑130 correctly is the most common source of problems. Based on user reports and discussions, here are the most important safety practices. Pinout Mapping and Interface 🔓 No signup
