Recall & Review

beginner

What does CSV stand for in data logging?

CSV stands for Comma-Separated Values. It is a simple file format used to store tabular data where each value is separated by a comma.

beginner

Why is CSV format popular for Arduino data logging?

CSV is popular because it is easy to create, human-readable, and compatible with many programs like Excel or Google Sheets for analysis.

beginner

How do you separate multiple sensor readings in a CSV file?

You separate each sensor reading with a comma. For example: temperature,humidity,pressure.

What Arduino function is commonly used to write data to an SD card in CSV format?

The File.print() and File.println() functions are used to write data to an SD card in CSV format.

beginner

How do you add a new line after each CSV data row in Arduino code?

Use File.println() to write the data row and automatically add a new line at the end.

What character is used to separate values in a CSV file?

A Comma

B Semicolon

C Tab

D Space

CSV stands for Comma-Separated Values, so commas separate the values.

Which Arduino library is commonly used to write CSV data to an SD card?

A SD

B Wire

C Servo

D SPI

The SD library is used to read and write files on an SD card.

How do you write a new line after a CSV row in Arduino code?

A File.print()

B File.write()

C File.println()

D File.read()

File.println() writes data and adds a new line automatically.

Why is CSV format good for data logging on Arduino?

A It is binary and compact

B It is easy to read and compatible with many tools

C It encrypts data

D It requires special software

CSV files are simple text files that can be opened by many programs like Excel.

Which of these is a correct CSV data row example?

A 23 45 67

B 23;45;67

C 23|45|67

D 23,45,67

CSV uses commas to separate values, so 23,45,67 is correct.

Explain how to log sensor data in CSV format on an Arduino with an SD card.

Think about how to write multiple values and save them as a line in a file.

What are the advantages of using CSV format for data logging in Arduino projects?

Consider why CSV is popular for storing tabular data.
