HI EVERYONE,
I'm Khaliil and I'm engineering student. I'm doing this project called Shake flashlight which is using Faraday's Law. I know the basic idea and how it works but i want to add some modification to slow down the drain of the capacitor to allow the LED to light more time…I have an idea but i don’t know to apply it, so can you help me with this please.
My question is:
How can I add a voltage sensor which can measure the voltage of the capacitor and than resets the resistor automatically which is connected 2V LED?
Example
I want to keep the LED 2Volts when the capacitor is fully (I’m using super-capacitor 16v) charged and I’m using resistor to protect the LED. when the capacitor reaches 5V i want the resistor to be 4-3ohm's and maintain the LED 2V(fully bright) but the capacitor reaches 3V, i want the LED to be like 1.6V(start getting dim and dimmer till its full OFF)
i can show you the circuit diagram if you want it...
I would real appreciate your help.
With Regards,
Khaliil
