Hi, i want to contol a 220v halogen lamp using microcontrolleur.i just started with the shematic on proteus.
The first circuit is for the zero crossing detector RB0/int.
The second is for firing the triac RB1.
And i want to display veff(lamp) on lcd.
What do u think about schematic, and any idea for programming (using micro c).
Thanks for your time.

Welcome to AAC!
If V1 is the mains supply you have one side of it directly grounded. That defeats the purpose of the opto-isolators.
As a side issue, doesn't Proteus have a way of re-positioning interconnection lines on the schematic? I find all those unnecessary kinks make reading the schematic difficult.

When i remove the ground the simulation fail, i found thats in proteus u need to add a ground to vsin.
I hope the schematic is clear now.
