I'm a student so I don't really have a solid background on electronics.
I'm wondering how to use a relay to switch between 2 DC sources, particularly a solar panel and battery to power our group's arduino project.
I've read lots of threads online saying to use an 'SPDT' relay, but I'm really unsure of how to wire them up.
