Ideas? How to make arduino sleep & wake up...

Thanks for the messages in my in-box.

Don't worry. I was the same when I started programming. We all have to start somewhere!

I think it would help to go right back to the beginning of the project? Here is a five point plan that may help:

  1. Did you get the adafruit DHT sketch to work with your sensors?

  2. Did you get a sample sketch for your RTC working? I can't test this properly, as I don't have DS1307, but it looks very straight forward

  3. Did you get a sketch to serial-print the correct time, date and sensor data to the serial monitor?

  4. So now that combined code, once fully working will form the core Data-logger methods eg void DataLog() {...tested code, known to work... }

  5. So once that combined code is fully working, try to incorporate the appropriate sleep and interrupt code in void loop() and make call to DataLog()

Cheers
