I have a mini water pump and a relay which turn on or off. humidicity sensor and light sensor in my project. How can I connect feed up my arduino with this board solar. i need a solar charger or battery.
The pump have an external battery. I only want feed up arduino with solar energy and make work this project.
I was looking at web about solar charges but this only output and input 5V and 2 amp
