Recently I began with arduino controllers and so far I have not had any problems…
I started a project that includes a seven-day monitoring of temperature.
It is necessary that in the course of one week, " Ardiuno " monitors temp. and if the temp. for those 7 days is not more than a given it neads to turn on heater for an hour or two.
The problem is the fact that I do not know which library to use or how to write a code which will do this.
If anyone has some advice ( idea ) I’d be much appreciative !! Thank you in advance!
