Unlocking Arduino's Hidden Memory: A Guide to Utilizing Built-In EEPROM

In this tutorial I will show you how to use Arduino built in eeprom to preserve data so it is not wiped out when Arduino is restarted.
We will be writing single byte values, sequence of byte values but also writing more complex data structures to that memory.
This video also provides information about all memory pools at your disposal when programing your arduino.

Hello Sir Mario I am always Thankful for your video. I really don't know about coding but I hope you may answer my question. Can someone who is proficient in coding record the Counted Value of a 4 Digit 7 segment LED driver that is driven by a MAX7219. Because as you said it can only store 4 bytes at a time, will a SD card on a SD card reader make an extended version of EEPROM without limit to its read and write count? I have a lot of questions, I wish I can understand as fast as possible. Thank You Sir keep those great videos coming.

i like this channel but it think the intros is knid boring but still GOOD channel. can you maybe do a "ghost hunter" machine?

Will watch your videos as you wish in 2020 🤣🤣🤣🤣 good video anyway 👍

I am having issue with the 3rd code "Remembering the sequences of lit led remebering duration" mine hangs when i press Record button on Pin A0.

So usually these memories never used by sketch like By all sketch of Example or Community?

hi, i am suffering from being too late for coding. We don't have English, I'm having trouble with translations. The video is super. I have to watch it many times.. It is needed for educational studies.. When pressed up to 4 times with a single button. Each pressed, 4 different LEDs will light up in a mixed manner.
These will remain registered in the eprom. It would be greatly appreciated if you make a video like this or share something useful, here's a little code hello everyone .. i subscribed waiting for your more videos

What kind of wires u used in breadboard instead of jumper cables?

What's the easiest way to clear the EEPROM back how it was before?
