thank you, my friend, you saved my life :)

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

[@ElectroDevices-yi4mj]

Great Tutor ... 🔥🔥

[@nuwannx]

Thank you soo much ❤

[@thanatlikitchontarn4923]

easy to understand thank you for video

[@amandaschulze5093]

Man that's one awesome video. You explained that verry well and well understandable! Great video

[@nikhiljoshi2769]

Superb

[@Gocast2]

Great explanation! learnt a lot

[@verlidesouza]

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

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.

[@RoboticsBackEnd]

Yes, for a 4 bytes number you just need a few more lines of code, but the procedure is exactly the same! Check out the end of this article where I explain how to store a 4 bytes (long) data type. You should be able to get inspiration from that to store a float. roboticsbackend.com/arduino-store-int-into-eeprom/

[@jhengineering3578]

Thanks for the replay! I ended up storing the float by incrementing the address. I've tried to replicate the code by using the long data type example code, but I get this error saying " invalid operands of types 'float' and 'int' to binary 'operator>>' ".

Thank You, Thank You

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

[@RoboticsBackEnd]

Here you can find an example to store 4 bytes: roboticsbackend.com/arduino-store-int-into-eeprom/

Merci beaucoup! .

[@manfredbogner9799]

Sehr gut

[@kimvuivoon4858]

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

[@RoboticsBackEnd]

"address + 1" means that if the current address is, let's say 178, then the "address + 1" will access the address 179

how to read and write a long integer in EEPROM?

[@imwhatim7259]

What about float value

[@RoboticsBackEnd]

A float is stored on more bytes than an int, so you'll have to split the number into more bytes.

Toll Danke

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