EEPROM for storing settings in Arduino - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to include the EEPROM library.

Arduino

#include <[1]>

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

AEEPROM.h

BServo.h

CSPI.h

DWire.h

💡 Hint

Common Mistakes

Including the wrong library like Wire.h or SPI.h instead of EEPROM.h.

The EEPROM library is included with #include <EEPROM.h> to use EEPROM functions.

2fill in blank

medium

Complete the code to write the value 42 to EEPROM address 0.

Arduino

EEPROM.[1](0, 42);

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

💡 Hint

Common Mistakes

Using EEPROM.read instead of EEPROM.write to store data.

Use EEPROM.write(address, value) to store a byte value at a specific address.

3fill in blank

hard

Fix the error in reading a byte from EEPROM address 1.

Arduino

byte value = EEPROM.[1](1);

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

Awrite

💡 Hint

Common Mistakes

Using EEPROM.write or EEPROM.put instead of EEPROM.read for reading.

Use EEPROM.read(address) to read a byte from EEPROM.

4fill in blank

hard

Fill both blanks to write a value only if it differs from the current EEPROM value.

Arduino

if (EEPROM.[1](5) != newValue) {
  EEPROM.[2](5, newValue);
}

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

Aread

Bwrite

Cupdate

Dget

Attempts:

3 left

💡 Hint

Common Mistakes

Using write for both reading and writing.

Not checking if the value is different before writing.

First read the current value with read, then write the new value with write if different.

5fill in blank

hard

Fill all three blanks to store and retrieve an integer value using EEPROM.put and EEPROM.get.

Arduino

int storedValue = 0;

EEPROM.[1](10, newValue);
EEPROM.[2](10, [3]);

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

Awrite

Bget

CstoredValue

Dput

Attempts:

3 left

💡 Hint

Common Mistakes

Using write and read instead of put and get for integers.

Not passing a variable to EEPROM.get.

Use EEPROM.put(address, value) to store complex data types like int, and EEPROM.get(address, variable) to retrieve it.
