Im hoping someone in this forum can help me because Im in need of saving 3 different values for the board to remember (hours, minutes, days) but I dont know how to do it. When I tried it started overwriting the values and I don't care if I need to convert all values into one or if there is an easier way but if someone could help me id really appreciate it.
Please post your full sketch. If possible you should always post code directly in the forum thread as text using code tags (</> button on the toolbar). This will make it easy for anyone to look at it, which will increase the likelihood of you getting help. If the sketch is longer than the forum will allow then it's OK to add it as an attachment. Don't put your code in some external file service like dropbox, etc. We shouldn't need to go to an external website just to help you. I do feel it's reasonable to post a link to code hosted on GitHub or similar code hosting sites since that's an platform specifically designed for this sort of thing
Please always do a Tools > Auto Format on your code before posting it. This will make it easier for you to spot bugs and make it easier for us to read. If you're using the Arduino Web Editor then you will not have access to this useful tool. I recommend using the standard Arduino IDE instead.
Reading and writing EEPROM is done on a byte base. If your values for hours, minutes and days are bytes, you can simply write them to different addresses in the eeprom and read them from those addresses.
If they are not bytes but integers (2 bytes on AVR), long integers or floats (4 bytes on AVR), you will have to write the individual bytes to consecutive addresses; e.g. the first byte of the integer to address 0, the second byte to address 1, the first byte of the next integer to address 2 etc.
You can look at the EEPROM.put and EEPROM.get methods that allow you to write any type of data without having to worry about the writing of the individual bytes of a variable.
