I'm currently designing a setup to show renewable energy in action to school children, water wheel, wind turbine etc for a local ecology centre I help out at.
What I'm struggling with is how to show the output power of the devices in a nice looking way rather than just a wattmeter.
What I would love to have is a circuit that lights up a series of LEDs at different power levels, problem is I have no idea how to do this. Anybody have any ideas?
Thank you for any help
