May be, Prahlad will finally inform us, what kind of driver he is using, so that this annoying guessing will come to an end???

I wonder, how people can expect any detailed help if information given by them is so lousy.
It took one day to get information about opto coupler, and may be another day to get information about driver?

And, like IJAZ stated, why not investing half an hour in drawing a schematic containing relevant information???

Seems to me, that some people are not really interested in getting their problems solved...
