Stepper motor with driver module in Arduino - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is a stepper motor?

A stepper motor is a motor that moves in small, precise steps. It turns a fixed amount each time it gets a signal, so you can control its position exactly.

beginner

What does a driver module do for a stepper motor?

A driver module controls the power and signals sent to the stepper motor. It helps the motor move step by step safely and correctly without damaging the Arduino.

intermediate

How do you connect a stepper motor to an Arduino using a driver module?

You connect the motor wires to the driver module, then connect the driver module to the Arduino pins for control signals and power. The Arduino sends commands to the driver, which moves the motor.

beginner

What Arduino library is commonly used to control stepper motors?

The Stepper library is commonly used. It helps send the right signals to the motor to make it move the correct number of steps.

beginner

Why do you need to set the number of steps per revolution in your code?

Setting the steps per revolution tells the Arduino how many steps the motor needs to turn one full circle. This helps control the motor's exact position and speed.

What is the main role of a stepper motor driver module?

A Store motor position data

B Increase the motor speed automatically

C Convert AC to DC power

D Control power and signals to the motor

The driver module controls the power and signals sent to the stepper motor to move it step by step.

Which Arduino library helps control stepper motors easily?

A Stepper

B Servo

C Wire

D SPI

The Stepper library provides functions to control stepper motors by sending the right signals.

Why do you specify steps per revolution in your code?

A To know how many steps make a full turn

B To set motor speed

C To power the motor

D To connect the motor to Arduino

Steps per revolution tell the program how many steps equal one full rotation of the motor.

What happens if you connect a stepper motor directly to Arduino without a driver?

A Motor runs faster

B Motor will not move

C Arduino may get damaged

D Motor will overheat safely

Stepper motors need more current than Arduino pins can provide; direct connection can damage the Arduino.

How does a stepper motor move?

A In continuous smooth rotation

B In small fixed steps

C Only clockwise

D Only counterclockwise

Stepper motors move in small, fixed steps, allowing precise control of position.

Explain how a stepper motor and its driver module work together with an Arduino to control movement.

Think about how each part helps the motor move exactly where you want.

Describe the steps to connect and program a stepper motor with a driver module using Arduino.

Start from wiring, then move to coding.
