Stepper Motor With Arduino UNO

Introduction: Stepper Motor With Arduino UNO

About: pursuing Bachelors in Electronics and Communication at Chandigarh University

Stepper motors are DC motors that move in discrete steps. They have multiple coils that are organized in groups called "phases". By energizing each phase in sequence, the motor will rotate, one step at a time.

Stepper motors are very useful in making projects which require precise positioning such as 3D printers. Due to few limitations we have one more type of motor called servo motors.

Limitations are : -

1. draw power even when not doing any work at all.
2. less torque at high speed.

3. No feedback mechanism like servo motor.

Moreover, Stepper motors require Motor drivers to connect with processing boards but we can connect servo motors directly to Arduino or esp32 board.

Step 1: Components Required

1. Stepper Motor - https://amzn.to/3013oAK

2. Motor driver - https://amzn.to/365Ke0p

3. Arduino UNO - https://amzn.to/2FJe9Rf

4. Jumper wires - https://amzn.to/3iqdBxM

5. Breadboard(optional) - https://amzn.to/3kdp4Rt

6. Arduino IDE software

Step 2: Circuit Schematic

Stepper motor works on 5v volts. therefore connect 5V of motor driver to ESP 32 Vin.

Motor driver --> Arduino UNO board

in1Pin --> 8

in2Pin --> 9

in3Pin --> 10

in4Pin --> 11

Vcc --> 5V

GND --> GND
