I am designing my first Arduino project, a solar powered LED lantern in a jar. I would like to know in advance how well my circuit will perform in a jar in direct sunlight, in a 90 F summer. The greenhouse effect and all.
Here is my design in progress:
Is this system safe to operate in a hot summer mason jar?
How concerned should I be about different batteries in this heat?
And what about summer rainfall? Does anyone sell rubber mason jar washers for extra water proofing the lid?
