Показать описание
Learn how to save an Int variable into the EEPROM of your Arduino. To do that you will need to split the integer into multiple bytes, and store each byte on a different address.

Hi, thanks for explaining in depth, how to read and write to EEPROM by manually shifting the bits, without relaying on predefined arduino functions. I have a question if I could replicate the procedure and store 4 byte floats? Thank you.

How do I need to shift when I want to use longs and doubles?

how to read and write a long integer in EEPROM?

If you can't store values over 32768 without it being negative, make sure you're using an unsigned integer!

is there some example on how to alter your code in order to save and read more than 2 bytes? I need 4 bytes to save a big number. your example works really well, but I can't find out how to change the code to save and read 4 bytes instead of just 2

Nice video, May I know what is mean by address +1?

Or just use the put() and get() functions
