hello, i am currently working on a school project, but i seem to struggle on how i am going to properly use the weekday() function from the arduino time library (Arduino Playground - Time)
the project should be related to a smart house and i and my group decided to design a smart function where the the house will be wamer when a person wakes up and coma back from work and lower the temperature/not heating up while the person is asleep or away
NOTE: there may be other flaws in this code as well
i would appreciate any help that might solve this problem. thanks!
#include <time.h>
//#define weekday(_time_) ((( _time_ / SECS_PER_DAY + 4) % DAYS_PER_WEEK)+1) // 1 = Sunday
const int sensorPin = A0;//temp sensor
int day, hour_start, hour_stop;
int day_of_week = weekday();
/*
tmElements_t tm; // declare a time structure element
RTC.read(tm); // Read the current date & time as TimeElements variable
tm.[color=blue]Hour[/color]++; // access the hour element and increase it
if (tm.Hour > 23) tm.Hour = 0; // check for overflow, after 23h goes to 0h
RTC.write(tm); // write it back
