I made a little windmill which is turning a small generator to light up an LED, but the voltage is too low even with high wind speed for the LED to glow. I thought maybe the electricity could be stored somehow maybe by a capacitor and released when the voltage is high enough, making the LED blink according to the wind speed.
I know little about electronics so I'm asking for help. Thank You.
Edit: What I want to know is how to make a circuit that charges up electricity from a low power source and discharge when the voltage is high enough. The frequency of discharges should increase when the power (wind speed) is increased. About the generator. It's actually a small electric motor. I tested it with another motor, connected their rotating heads together, applied 5V to one of them and measured about 4V coming from the other, so I thought it's not a bad idea to use it as a generator. This is a really small project and it shouldn't be taken too seriously.
