This Course is Perfect For
Whether you're starting from scratch or switching careers — this course is designed with your success in mind.
Learn how to store and retrieve data permanently on your Arduino using its built-in EEPROM memory! This comprehensive course teaches you how to effectively use EEPROM to create smarter, more robust, and user-friendly electronics projects that retain data even after power loss or resets.
Unlike regular RAM, EEPROM memory is non-volatile, meaning your data is saved even when the device is turned off. This is perfect for saving critical information such as:
- Device settings
- User preferences
- Calibration values
- Last known sensor readings
- Configuration flags
- Login credentials and more
Throughout this course, you’ll not only learn the theory behind EEPROM memory, but also get hands-on experience with practical examples, real-world applications, and memory-saving techniques that prevent wear and ensure long-lasting project performance.
What You Will Learn:
- Introduction to Arduino Memory Architecture: RAM vs Flash vs EEPROM
- EEPROM basics: How it works and why it’s important
- How to read and write bytes to EEPROM
- How to store integers, floats, and strings
- Writing and reading custom data structures (using structs)
- EEPROM wear and how to avoid it (write cycles, memory endurance)
- Efficient memory usage: EEPROM.update() vs EEPROM.write()
- Using external EEPROM modules with I2C (for extra memory space)
- Real-world applications: saving state across power loss or reset
