[Ronja] Fast switching of strong LEDs

[Pramod yaduvanshi]

Hi ,

You can try and use H bridge circuit and flash it if 1...10us is all you are
looking at .
Just replace the stepper motors with your LED and use longer 2 wires .There
are several H Bridge available commercially but you can build a simple one
using high current Transistors !!
