The L293D Motor Driver Shield for Arduino Uno is probably one of the most versatile on the market and features 2 servo and 4 motor connectors for DC or stepper motors. That makes it a great shield for any robotic project.

This Arduino compatible motor Driver shield is a full-featured product that it can be used to drive 4 DC motor or two 4-wire steppers and two 5v servos. It drives the DC motor and stepper with the L293D, and it drives the servo with Arduino pin9 and pin10.

The shield contains two L293D motor drivers and one 74HC595 shift register. The shift register expands 3 pins of the Arduino to 8 pins to control the direction of the motor drivers. The output enables the L293D is directly connected to the PWM outputs of the Arduino.

Firmware of L293D Motor Driver Shield for Arduino Uno

1. Arduino Stepper/Servo software library with microstepping support.
   To install, click on Download in the top right corner, select zip and uncompressed the folder.
   Rename the folder to AF-motor (check that the renamed folder contains the .cpp and .h files) and install it into the Arduino sketches/libraries folder. For information on how to use and install libraries, see our tutorial! This version now works with the Mega. Public domain!
2. AccelStepper library with AFMotor support. This library allows for advanced stepper control including acceleration and deceleration, and concurrent stepper control!
