Hi! I would like to do a project where I connect a small LED to solar cell and dynamo motor as two circuits connected by a SPDT switch, so I can power the light with the power source of my choosing. I don't really know much about circuits or where to start. Like where does voltage and current and resistance play part and what should I know about it for a project like this? How does I connect the LED to wires or the switch? Positive to negative? I am sure some one here can help me and I hope a project like this is simple for you. Also can you explain to me the materials I'd need for a project like this? Thanks and feel free to ask more questions! Any help is greatly appreciated!
