Using multiple libraries together in Arduino - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to include the Wire library for I2C communication.

Arduino

#include [1]

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

A<SPI.h>

B<Wire.h>

C<Servo.h>

D<EEPROM.h>

💡 Hint

Common Mistakes

Including SPI.h instead of Wire.h

Forgetting the angle brackets <> around the library name

The Wire library is included with #include to use I2C communication.

2fill in blank

medium

Complete the code to initialize the Serial communication at 9600 baud.

Arduino

void setup() {
  Serial.[1](9600);
}

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

Binit

Cstart

💡 Hint

Common Mistakes

Using Serial.start instead of Serial.begin

Using Serial.init which does not exist

Serial communication is started with Serial.begin(baud_rate).

3fill in blank

hard

Fix the error in the code to read data from the Wire library.

Arduino

Wire.[1]();
int data = Wire.read();

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

ArequestFrom

BendTransmission

CbeginTransmission

Dwrite

💡 Hint

Common Mistakes

Using write instead of requestFrom

Using beginTransmission when reading data

To read data from a device, Wire.requestFrom(address, quantity) is used.

4fill in blank

hard

Fill both blanks to send data using SPI library.

Arduino

SPI.[1]();
SPI.[2](0xFF);

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

Abegin

Btransfer

Cend

Dwrite

Attempts:

3 left

💡 Hint

Common Mistakes

Using SPI.write which is not a standard SPI function

Forgetting to call SPI.begin before transfer

SPI communication starts with SPI.begin() and sends data with SPI.transfer().

5fill in blank

hard

Fill all three blanks to initialize Servo and set its position.

Arduino

#include <Servo.h>
Servo [1];
void setup() {
  [1].[2](9);
  [1].[3](90);
}

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

💡 Hint

Common Mistakes

Using begin() instead of attach() for Servo

Not naming the Servo object

Create a Servo object named myServo, attach it to pin 9, then write 90 degrees.
