Hello, what I'd like to do is to build some kind of calendar into the arduino sw in order to trigger the "up" signal of a digital pin on specific dates. What bothers me are:
- General feasibility (i.e.: can this be done?)
- Power consumption (i.e.: the arduino will have to be disguised and battery powered, how long can the sw run before all my batteries are drained/how many batteries should I pack?)
- Is there a better solution? (i.e. are there any external components that can wake my arduino pins on certain dates, with less code/power consumption?)
Thanks a lot.
