Motor Driver Connection Diagrams

Use these quick diagrams to connect DC, stepper, and servo motors to your motor driver and Arduino.

1. DC Motor + L298N Driver + Arduino

         +12V Supply
           (+)  (-)
            |    |
           +V   GND  (L298N)

L298N Motor Outputs:
 OUT1 ─── DC Motor ─── OUT2   (Motor A)
 OUT3 ─── DC Motor ─── OUT4   (Motor B - optional)

L298N Inputs → Arduino:
 IN1  ───────────── D8
 IN2  ───────────── D9
 IN3  ───────────── D10
 IN4  ───────────── D11
 ENA  ───────────── D5   (PWM for Motor A speed)
 ENB  ───────────── D6   (PWM for Motor B speed)

Power & Ground:
 5V (Arduino) ──> 5V (L298N logic, if required)
 GND (Arduino) ──┴── GND (L298N) ── GND (Power Supply)

Always share ground between Arduino, driver board, and power supply.

2. Stepper Motor + A4988 Driver + Arduino

A4988 Driver Pins:
 -----------------------------
 VMOT  → +12V (Stepper supply)
 GND   → Power GND
 VDD   → +5V (Arduino)
 GND   → Arduino GND

Motor Coils:
 2B, 2A, 1A, 1B → Stepper motor wires
 (check datasheet for coil pairing)

Control Signals → Arduino:
 STEP  ───────────── D3
 DIR   ───────────── D4
 ENABLE (optional) ─ D2

Shared Ground:
 Arduino GND ──────── Power GND ─────── A4988 GND

Set current limit on the A4988 using the potentiometer before running the motor.

3. Servo Motor + Arduino + External Supply

External 5–6V Supply:
  (+) ───────────── Servo V+
  (-) ───────────── Servo GND
                      |
                      └──── Arduino GND (common ground)

Servo Signal:
  Servo Signal (Orange/White) ───── D9 (PWM pin)

Arduino:
  Powered by USB or separate 5V supply

Do not power large servos directly from the Arduino 5V pin; use an external supply with common ground.

Top 5 Motor Driver Circuits for Beginners

Bidirectional DC Motor Control with L298N: Use an L298N or L293D module to drive one or two DC motors with speed control (PWM) and direction control using two digital pins per motor.
Simple H-Bridge with Transistors or MOSFETs: Build your own H-bridge using four NPN transistors or MOSFETs to understand how motor direction is reversed at the circuit level.
Stepper Motor Positioning with A4988: Use an A4988 driver and Arduino to move a stepper motor a precise number of steps and microsteps for sliders, CNC, or 3D printer axes.
Servo Sweep Circuit: Control a single servo using Arduino’s Servo library to sweep from 0° to 180°, perfect for learning PWM and position control.
Dual Motor Robot Car with L298N + Joystick: Connect two DC motors to an L298N and use joystick or Bluetooth input to control forward, backward, and turning motions.

Robotics Projects Using Motor Drivers (Tutorial Ideas)

Line Follower Robot: Use an L298N driver with two DC motors and IR sensor array. The Arduino reads sensor values and adjusts motor speeds to stay on a black line.
Obstacle Avoidance Robot: Pair a motor driver with two DC motors and an ultrasonic sensor. When an obstacle is detected, the controller slows, stops, or turns the robot.
Robotic Arm with Servos: Use multiple servo motors driven from an external 5–6V supply. Control each joint via Arduino to pick and place small objects or draw simple shapes.
Mini CNC / Plotter with Steppers: Use stepper motors and A4988 drivers on X and Y axes. The Arduino interprets simple G-code or drawing commands to move a pen over paper.
Smart Conveyor or Slider: Use a DC motor + encoder or stepper motor with driver to build a small conveyor belt or camera slider, controlled by buttons or a simple UI.

1. How to use a L298n motor driver?

The L298N is a dual-channel H-Bridge motor driver capable of driving a pair of DC motors. That means it can individually drive up to two motors making it ideal for building two-wheel robot platforms. It consists of pins for motor power supply(Vs), ground and 5V logic power supply(Vss).

2. What does a motor driver do?

A motor driver interfaces a motor with a microcontroller and external power source, with safety features built in to prevent back emf that may be generated by the motor. A motor driver is essentially an IC (Integrated circuit) chip which used to control the motors in robots in varied applications

3. Which motor driver is the best for a robotics project?

Motor drivers come in all forms of shapes and sizes, depending on the rating, maximum supported voltage and current, number of motor connections required, safety features, etc. For a robotics project, you may need a motor driver that supports at least 4 motors.

4. What is the difference between a motor driver and a motor controller?

Motor driver acts as an interface between motor and microcontrollers while also providing external power source to the motors, while motor controllers also have built in microprocessors to control the motors thereby eliminating the need of a microcontroller to run the motor.

5. How do I choose and buy a motor driver?

Motor drivers must be chosen based on the power rating, number of available motor connections and safety features. Motor drivers are classified on the basis of:-

Maximum Supply Voltage
Maximum Output Current
Rated Power Dissipation
Load Voltage
Packaging Type
Number Of Outputs.

6. What is an Arduino motor driver?

A motor driver made for Arduinos is typically referred to as an Arduino motor driver. These drivers will operate at 5V while having provisions to connect external power supply for the motors itself

7. Why do I need a motor driver?

Motors can generally effectively be used if it gets adequate voltage and current that typical microcontrollers do not provide. Thus motor drivers are used to overcome, as it supplies power for all the motors with an external power source.
