  • Thanks, it works. My problem now is that I can only use EEPROM.write(); inside of a function and that prevents me from creating a global variable that all my function can use. Commented Jun 10, 2016 at 15:56
  • @IsabelAlphonse ??. The EEPROM.write() is a function and has to be used within a function. I think you need to start with the basics TBH. What I also think you mean is the read part. I have edited my answer to include the code you have written that works. Commented Jun 10, 2016 at 16:29
  • @IsabelAlphonse please can you mark one of the answers as accepted so that the StackExchange system doesn't bump it up in a few weeks and also to allow others to find it more easily when searching for the same problem. Commented Jun 10, 2016 at 17:13

  • You said: "The EEPROM also doesn't take to being written or read to often as EEPROM can wear very quickly. " Datasheet says: Memory Flash Endurance: 10,000 Write/Erase Cycles, EEPROM Endurance: 100,000 Write/Erase Cycles. So EEPROM can be written ten times more often than the flash memory.
