I’m new to Arduino and am working on a project- I just got my new load cell and am ready to build my device, but realized I need to store data from the sensor on the board while it’s in use, and later upload that to my PC for analysis- I can’t have the computer connected during use. Is there a solution I could find by hitting local shops rather than having to wait for an online order to arrive? I’m not sure what I need to get that is usable with the Arduino and would allow temporary data storage.
depending on the Arduino you have, the size of your sketch and the amount of data storage you need, you could consider to use the EEPROM library and store your values in ‘flash memory’. The values will be retained after reset/reboot in flash memory.
The OpenLog would be the easiest way to log your data since you won’t probably need to modify your code much, if at all.
Another alternative would be to add a SD card to your setup to log data too, but that would require you modify your code to support the SD card. If you’re good at programming, this would be a slightly less expensive option.
