hello ahmed ,

nice concept… i think you can use it as you do in seven segment mutiplexing technique… i dint tried that yet but that idea must work… instead of connecting the cathod directly to microcontroller use ULN… and the common pint of ULN can be used as a multiplexing point… i will try that concept and paste the ckt here… till the tym you also try and let me know till where you have reached… once again apprecaite your idea.. all d bst i will back to you soon…
