Mr. Manjeet Singh,

A good web site which has a description of how to handle Vacuum Fluorescent Display's (VFD) can be found at the below address.

You can also see a schematic on how to interface LED's (same idea as VFD's) at the below address.

There are also other examples of how to interface embedded processors to LED clocks on the Internet but I don't have any addresses handy.

Good luck,

Charles Bannister
