Tell us about yourself!
Thanks GodsTale, Yes, EEPROM is all storage Arduino has. (As RAM can't store data even if power switches off). Do professional health bands use SD card module or just another EEPROM chip? For example say Mi band uses which stuff for storage of data bits temporarily?
Hi @GodsTale,Nice instructable. Thanks. Very useful. I have a concern. What if I have to store some data in tracker itself temporarily (May be for a day if user don't want to keep smartphone connected). So, that he can sync up tracker with his phone once in a day. How can we achieve this? Any extra hardware component or will it be just a extra code piece? Thanks./perrygarg
