I have a solar panel from a cheap Walmart device I tore down. Hooking it to a Multi-Meter shows it’s about 2.25V (probably supposed to be 2.5V but runs a little low?).
What’s something useful I can do with it?
You must log in or # to comment.
Do you have any low power IOT or sensor projects? Humidity or soil moisture monitor perhaps?
None on me, though I could probably purchase one or two for my garden.
