amount of wind (input) = number of LEDs Lit? Answered
Good afternoon, Im making an exhibition piece that will have children working a set of bellows that are connected to a (pretend) blacksmiths forge. What I need to represent is the more the bellows are pumped the more the "embers" will glow. Im thinking a turbine tachometer that leads to an LED driver set to display as Bar so the faster the turbine spins the more LEDS are lit, or they trigger a series of LEDs to light (this thing has to get pretty bright not sure one LED per step will do it.
Trouble is im good with the theory and pretty good with the practical its just the technical that is letting me down.
If anyone could see there way to giving this some thought and maybe doodling a circuit diagram / shopping list that would be awesome.
