![]() To design this Arduino Motor Driver Shield, we have chosen the online EDA tool called EasyEDA. How to Use Shift Register 74HC595 with Arduino Uno.Controlling Multiple Servo Motor with Arduino.Interfacing Stepper Motor with Arduino UNO.You can also learn interfacing of all these motors and shift register with Arduino in our previous articles without using the Motor Driver shield: You can use the given code (in the end) or use your own code for controlling the motors according to your application. You just have to fix the shield over Arduino and control motors using this shield. With this shield, making motor based projects are super easy with Arduino. If DC motor speed controlling is not necessary make these pins HIGH. M1PWM, M2PWM, M3PWM, and M4PWM are used for controlling DC motor speed.ST, DS, OE, SH, and MR is used for driving S hift Register.It has jumper pins to select either 12v Power to Motors or 5v power to motors. L293D motor driver is signaled by using a shift register 74HC595 and the shift register is signaled by using the Arduino. It has screw terminal for conncecting motors wires. This board can be controlled by using Arduino like Arduino UNO, Arduino Mega and similar boards. This Arduino motor driver shield can be used to build DC or stepper motor based projects like a Robotic Arm, Line Follower, land robbers, maze followers and many more projects. ![]() Here two L293D Motor Driver ICs are used for driving motors and an 8-bit shift register for controlling them. Compatible with Arduino UNO and Arduino Mega, this motor driver shield can operate 4 DC motors or 1 stepper motor and 2 servo motors at a time. In this DIY session, we make an Arduino Motor Driver Shield to drive DC motors, stepper motor and Servo Motor.
