Hw 130 Motor Control Shield For Arduino Datasheet Free __exclusive__ Here

to expand 3 Arduino pins into 8 control lines for the H-bridges. Direction Control

Separates the Arduino power from the motor power. You must connect an external power supply (4.5V–25V) to the EXT_PWR screw terminal to run the motors. The Arduino must be powered independently via USB or its own DC jack. Software Installation and Libraries

Keeps electrical noise and current spikes isolated from the microcontroller. 5. Software Integration and Code Example

// --- Stop --- analogWrite(M1_SPEED, 0); delay(1000);

Plug the Arduino USB cable into your computer to upload code and supply logic power [1]. 💻 Arduino Code Example

Can drive up to 4 bi-directional DC motors or 2 stepper motors (unipolar or bipolar). to expand 3 Arduino pins into 8 control

The shield simplifies wiring by utilizing a serial-to-parallel shift register, which frees up most Arduino digital pins. Component Pin Usage on Arduino Pins 11, 3, 5, 6 PWM pins for speed control. Shift Register Pins 4, 7, 8, 12 Used to set motor direction via AFMotor library. Servo Motors Pins 9, 10 Directly connected to Arduino's high-resolution timers. Analog Pins Remain free for use with sensors or other inputs. Digital Pins Not used by the shield and available for general use. Power Management

The HW‑130 is a popular clone of the original . Because the original Adafruit design has been discontinued, the HW‑130 often serves as a low‑cost alternative that maintains full pin and code compatibility. The shield acts as a bridge between the low‑current logic pins of the Arduino and the high‑current demands of various motors. It also uses a 74HC595 serial‑to‑parallel converter to reduce the number of Arduino pins required, leaving more digital and analog pins free for other sensors and components.

The HW-130 maps the L298P controls to the Arduino as follows: The Arduino must be powered independently via USB

Many Arduino tutorials recommend keeping the motor power supply completely isolated from the Arduino’s power supply. This is especially important when you are also running sensitive modules such as Bluetooth modules, sensors, or servos. Power the Arduino via its USB port or a dedicated 9 V adapter, and power the motors through the EXT_PWR terminal.

The HW-130 shield offloads high-current demands from the Arduino board to safely power inductive loads [1]. 2 x L293D Dual H-Bridge drivers [1]
