The L293D Motor Driver/Servo Shield for Arduino 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 can be used to drive 4 DC motors 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 pins 9 and pins 10.
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 to be directly connected to the PWM outputs of the Arduino Uno R3.
Firmware:

Click To Read More There exist three scenarios when it comes to supplying power for the motors through the shield. The L293D motor driver shield includes two L293 motor driver ICs and a 74HC595 shift register IC. The shield has several important components. The L293D is a dual-channel H-bridge motor driver that can control two DC motors or a stepper motor at one time. As there are two L293D ICs on the shield, it’s technically capable of controlling a total of four DC motors. This is ideal for two and four-wheel robot platforms. The IC consists of two H-bridge to control the motors, each delivering p to 0.6A to a motor. The 74HC595 is an 8-bit serial input and serial/parallel output shift register. It’s used to extend four Arduino GPIO (or another microcontroller) to eight-direction control pins for two of the L293D motor driver ICs. Arduino’s L293D motor driver shield is compatible with Arduino Mega and UNO. The shield can be fitted on top of the Arduino board. In such cases, six analog pins including pins 2 and 13 remain free for use. To control the servo motor, use: To control the DC motors, use: To control the stepper motors, use: Vayuyaan believes in satisfied customers, so whatever the product is we first import them and then test them for their supplier-defined and standard capabilities. After all the possible quality checks, we make the product available to our customers. Read LessPower Supply To L293D Motor Driver Shield:
