Stepper motor basics in Arduino - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to include the Stepper library.

Arduino

#include <[1]>

Drag options to blanks, or click blank then click option'

CStepper.h

DSPI.h

💡 Hint

Common Mistakes

Including Servo.h instead of Stepper.h

Forgetting the angle brackets <>

The Stepper library controls stepper motors. Including Stepper.h allows us to use its functions.

Complete the code to create a Stepper object with 200 steps per revolution.

Arduino

Stepper myStepper([1], 8, 9, 10, 11);

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 100 or 400 steps which may not match the motor

Confusing pin numbers with steps

Most common stepper motors have 200 steps per revolution. This number tells the library how many steps to make a full turn.

3fill in blank

hard

Fix the error in setting the motor speed to 60 RPM.

Arduino

myStepper.[1](60);

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'speed' as a function instead of 'setSpeed'

Trying to set speed directly as a variable

The correct function to set speed in RPM is setSpeed(). Other options are invalid or do not exist.

4fill in blank

hard

Fill both blanks to move the motor 100 steps forward.

Arduino

myStepper.[1]([2]);

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'move' instead of 'step'

Using 200 steps instead of 100

The step() function moves the motor a number of steps. Here, 100 steps moves it forward.

5fill in blank

hard

Fill all three blanks to create a Stepper object with 4 control pins and 100 steps per revolution.

Arduino

[1] [2]([3], 6, 7, 8, 9);

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Swapping the order of steps and pins

Using variable names instead of class name

The first blank is the class name Stepper. The second is the object name motor. The third is the number of steps 100. Using four pins indicates 4 control pins.
