Hw 130 Motor Control Shield For Arduino Datasheet !free!

The HW-130 Motor Control Shield for Arduino Go to product viewer dialog for this item.

It is a cost-effective alternative to official shields, especially popular among hobbyists and educators building small robots, automated systems, and various motion-control projects.

The HW-130 Motor Control Shield is a versatile, budget-friendly expansion board designed for Arduino enthusiasts and robotics builders. Based on the classic L293D dual H-bridge motor driver IC, this shield allows you to control multiple motors simultaneously without a messy tangle of jumper wires.

| Connector | Label | Function | |-----------|-------|----------| | | A+ A- / B+ B- | DC Motor A & B (Channels 1 & 2) | | M3 / M4 | C+ C- / D+ D- | DC Motor C & D (Channels 3 & 4) | | Servo 1 | SIG - VCC - GND | Servo control (5V or external) | | Servo 2 | SIG - VCC - GND | Servo control (5V or external) | | Ext PWR | GND – VIN (or VS) | External motor power input (6–12V DC) | | Arduino pins | Stacked headers | Digital I/O 4,5,6,7,8,9,10,11,12,13; A0-A5; 5V; GND; RESET | hw 130 motor control shield for arduino datasheet

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.

Serial.println("Backward at speed 100"); motor.run(BACKWARD); // Spin counter-clockwise motor.setSpeed(100); delay(2000);

Used to interface with the 74HCT595 shift register to handle motor direction. The HW-130 Motor Control Shield for Arduino Go

If you are using small 5V motors (like cooling fans), you can power everything from the Arduino.

// Create motor objects on channels 1 and 2 AF_DCMotor motor1(1); AF_DCMotor motor2(2);

Ultimate Guide to the HW-130 Motor Control Shield for Arduino Based on the classic L293D dual H-bridge motor

Key onboard components:

The Arduino and the motor shield are isolated. You must supply logic power to the Arduino (USB/DC jack) and motor power to the EXT_PWR terminal separately. This is the recommended configuration. Motor Terminal Blocks

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

// Left motor on M1, Right motor on M2 AF_DCMotor motorLeft(1); AF_DCMotor motorRight(2);

If the jumper is shorted, the Arduino and the motors share the same power source. It is highly recommended to remove the jumper and use separate power supplies to avoid resetting the Arduino due to voltage spikes. Motor Connections
