Hi guys... If anyone here is good at circuit diagrams, could someone draw me a crude one for a solar torch (a torch with rechargeable batteries that are charged by the solar panel). It just has to be a rough outline, as I know the basics of circuits and circuit diagrams, however I'm not sure about how the solar panel (I'm pretty sure there needs to be some sort of flow controller so the electricity can't flow from the batteries back to the solar panel).
Thanks you
Thanks you
