I need to make photographs of plants outside in the garden regularly.
I plan to do it with a Raspberry Pi Zero connected to a battery.
The pi should turn on every day once or twice at the same time. When the pi boots up it takes a photo then shuts down. So the powering should run maximum 5 minutes at once. That's more than enough. It would be ideal to run this cycle for several weeks, of course it depends on the battery.
I am thinking to control the power and the switch timing with an Arduino nano. I've read that in deep sleep the power consumption of Arduino is very low.
Could you help me on this? I am quite a newbie in electronics. Some years ago I tried Arduino, but I have only a very little experience on it. What does this project needs beside the nano? I would like to make the most simple solution with the least soldering
Thank you
