The L293D Motor Shield for Arduino is a versatile motor driver expansion board designed to be compatible with various Arduino boards. It enables easy control of DC motors and stepper motors, making it ideal for robotics, motor control projects, and other applications requiring motor driving capabilities.
Key features include:
Dual H-Bridge Motor Driver: The L293D chip on the shield contains two H-bridge motor driver circuits, allowing it to control two DC motors or one stepper motor.
Current Sensing: The shield includes built-in current sensing resistors to monitor the motor current.
Compatibility: Designed to fit directly onto most Arduino boards, including Uno, Mega, and similar form-factor boards.
External Power Input: Provides a terminal block or power jack for connecting an external power supply to power the motors separately from the Arduino.
Built-in Protection: Includes diodes to protect the shield and the connected Arduino from voltage spikes generated by the motors.
Screw Terminals: Terminal blocks or screw terminals for easy connection of motor wires.
PWM Control: Allows speed control of DC motors using PWM signals from the Arduino.
Flexible Control: Can be controlled using simple digital I/O pins on the Arduino board, making it easy to integrate into Arduino projects.
The L293D Motor Shield simplifies motor control tasks by providing an easy-to-use interface between Arduino boards and motors. Whether you're a beginner experimenting with motor control or an experienced developer building complex robotic systems, this shield offers a convenient and reliable solution for driving motors with Arduino.
