L293D Motor Driver Shield for Arduino – Description

With 4 motor and 2 servo connectors for DC/stepper motors, the L293D Motor Driver Shield is one of the most versatile and sought-after units on the market. Users can find it as a productive shield to embed in robotic projects.It is one of the finest ways to control and manage stepper, DC, and servo motors. It comes to be more effective in case your project involves Arduino UNO/Mega like in CNC.

There is also an additional motor driver – L298N, but it controls only the DC motors. Moving to the motor integration under question, it is a fully-featured device that is capable of driving 4 DC motors or two 4-wire steppers. Further, it drives the DC motor using L293D and servo motors with Arduino pin9 and pin10. You can see a 74HC595 shift register and two L293D motor drivers integrated with the shield.

Structure of the L293D Motor Driver Shield

In terms of structural formation, the shield is based on the L293D IC to run 4 bi-directional DC motors 2 servo motors, and 2 stepper motors. It is precisely compatible with the Arduino UNO/Mega circuits. You should take into account that each channel of this module features the maximum current of 1.2A. It doesn’t work in the case the voltage measures less than 4.5V or more than 25V.

Furthermore, the L293D is an H-Bridge (dual-channel) motor driver that can operate a pair of DC motors or a single stepper motor. The motor shield houses 4 H-Bridges with each bridge delivering up to 0.6A to the motor. Additionally, the L293D shield also integrates a 74HC595 shift register that has 4 extended digital pins of the Arduino.

L293D Motor Driver Shield - How to Use?

When it comes to using the L293D Motor Shield, you will see that 6 analog pins, pin 2 and pin 13 are free. But pin 2, 9, and 10 are used when you have to run Servo Motor using this shield. While running the DC motor, different pins are used in the following pattern – pin11 for #1, pin3 for #2, pin5 for #3, pin6 for #4, etc. Concerning a stepper motor, pins 11 and 3 for #1, pins 5 and 6 for #2, and pins 4,7,8, and 12 for all of them are used.

L293D Motor Driver Shield – Power Supply Considerations

The power supply mechanism also demands a careful approach for L293D motor integrations. You should plug into the DC jack of the Arduino board if you’re using a single power supply for both Arduino and motors. Also, you need to get the power jumper of the motor in the right place to get it working precisely. This method is potent in the motor supply voltage is less than 12V.

On the other hand, you can execute two different power supplies for motor and Arduino. You can use the USB to power the Arduino and a DC power supply to power the motor.
