Real-Time Data Logging with Arduino: Mastering millis() and SD Cards

Join me in this exciting Arduino tutorial as I build a powerful temperature logger that can run for days, even weeks! In just 15 minutes, you'll learn how to create a data-logging device that captures real-world temperature data and stores it on an SD card.
Key Highlights:

Leverage the power of the millis() function to implement non-blocking data logging
Interface an Arduino with a DHT22 temperature sensor and SD card module
Format sensor data into a CSV file for easy analysis
Explore practical applications, from home energy optimization to greenhouse monitoring
Customize the project by adding more sensors or adjusting the logging interval

But first, we've got a challenge for you: Can you figure out how to log data every minute without using the delay() function? Stick around, and you'll discover the ingenious solution that keeps your Arduino responsive and efficient.
Whether you're a beginner or an experienced maker, this video will equip you with the skills to build your own versatile data logger. Get ready to turn your Arduino into a powerful environmental monitoring tool!
Don't forget to like, subscribe, and share your project creations in the comments. Let's dive in and master real-time data logging together!

BEST vid on SD data logging. Thank you for NOT adding music. Minor tip. Back up that one camera so the close up of your face is not that close. Thank you!!!

This is awesome! I always thought I'd need to order some type of I2C driven SD-card board, but now have a use for one of the many free Adapters that come with new Micro-SD cards. Tried it out today. Thanks for the tutorial!

Why is there no time stamp in the logged file?

Thank you : great tutorial
Question: do we need to explicitly close the log file we create before we can safely remove the SD card and use the file in a separate computer?

Considering the cost of an SD card module, why on earth would you destroy an SD card to do this?
