Solar Powered Arduino!?
Spring is springing here in the U of K, and this weekends task, is to rip down the RUBBISH shed on the allotment, and construct a HEROIC crystal fortress of solitude out of sturdy second hand glass doors and windows. The plan is for it to be greenhouse type structure.
I see this as my next arduino project! I intend to pick up an SD card shield, and get some data logging going on.
Light levels, indoor temperature, outdoor temperature, moisture levels, etc etc.
I was also thinking, i COULD use the arduino to automagically open a tap to top up seed trays with water from a water butt, or open a louvre to let cool air in should the house get too hot!
However, being an allotment, i have no electricity source! My intention at the moment is to pick up a cheapo solar light or similar, and power the unit by trickle charge solar in the day? i am currently researching how likely this is to work!
has anyone done anything similar?
any reccomendations on how to go about arranging a solar power setup?
does a servo use power all the time it is connected? i figure this would be the best way to control a tap, but dont want it to constantly drain a low capacity power supply....
