Hello,
I'm electronic beginner, I made a simple circuit with attiny13, humidity sensor and 3 leds. I want to put it in a small case and power with battery.
I also don't want to charge it. So I think solar cell is the best solution. I saw small ones but I can't find it. I also don't know what battery to choose for the solar cell to charge it. My circuit works at 3.3V. It is posible to do?

Find a garden solar light that uses a 3.2V LiFePO4 battery.
The light will have the solar panel, battery and charging circuit all ready for you to use.
