Stepper motor with driver module in Arduino - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to define the step pin for the stepper motor driver.

Arduino

💡 Hint

Common Mistakes

Using a pin number not connected to the step input of the driver.

The step pin is connected to digital pin 9 on the Arduino.

medium

Complete the code to set the direction pin as an output in the setup function.

Arduino

void setup() {
  pinMode([1], OUTPUT);
}

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

💡 Hint

Common Mistakes

Setting the wrong pin as output or forgetting to set the pin mode.

The direction pin controls the rotation direction and must be set as output.

3fill in blank

hard

Fix the error in the loop to make the motor step correctly.

Arduino

digitalWrite(stepPin, HIGH);
delay([1]);
digitalWrite(stepPin, LOW);
delay(1);

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

💡 Hint

Common Mistakes

Using zero or negative delay causing no movement or errors.

A delay of 10 milliseconds between steps allows the motor to move smoothly.

4fill in blank

hard

Fill both blanks to complete the code that sets the motor direction and steps it.

Arduino

digitalWrite([1], HIGH);
digitalWrite([2], HIGH);
delay(10);

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

💡 Hint

Common Mistakes

Confusing stepPin and dirPin or using unrelated pins.

Set the direction pin HIGH to choose direction, then pulse the step pin HIGH to move one step.

5fill in blank

hard

Fill all three blanks to create an array holding the pin numbers for stepPin, dirPin, and enablePin.

Arduino

const int pins[] = { [1], [2], [3] };

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

💡 Hint

Common Mistakes

Including unrelated pins like ledPin or missing one of the motor control pins.

The array holds the pin numbers for step, direction, and enable pins used by the driver.
