Hello sam,

First, let me get few things straight,
1) you have already designed a digital speedometer ?
2) i did not get it when you say "whether this is possible in the digital speedometer without designing new speedometer???"

yes, it is possible to incorporate the speed limit warning in the main speedo code itself without any other additional hardware.

check my digital Speedometer cum odometer project published in november -2008 issue of "EFY". you can modify the source code to your requirements.
