quick noob question

i am starting a project where my arduino is a heater controller

i want a LCD to display current temp and desired temp

i then want to be able to adjust the desired temp with buttons

easy so far

but how do i save the setting into the arduino so if i loose power the setting is saved rather than having to adjust it on the sketch then upload again

thanks

steve :)

Check out EEPROM

The EEPROM is where you store data that needs to be remembered even when the power gets turned off.

awesome

thank you :slight_smile:
