I currently have a 7 segment 4 digit display working in unison with a RTC 1307 chip to display the time. I however require my project to be sustainable and have it run off batteries which are powered via a renewable energy source.
So while browsing through forums, I have come across a deep sleep mode for the Arduino and was thinking of having my display on sleep mode until someone triggers a capacitive touch sensor to wake the arduino from sleep and light up my display again showing the appropriate time. (I am using a RTC chip not a RTC module so I am foreseeing some errors in showing the appropriate time since I do not have the CR2032 battery with me at the moment)
I was just oblivious yet curious as to how I was going to implement the above into my code as I am fairly new to programming with Arduino.
Any tips or help would be greatly appreciated!
