incandescent light bulb dimmer with atmega16

[legendaryvr]

Hie guys
I want to design a ac bulb that dims at different levels say 20%,60% and 100% . The dimming will be controlled by use of triac and atmega 8. I am stuck i dont know where to start so if there is anyone who can help me with a code and circuit i will be so grateful. Im trying my best to build the circuit but the problem is that my multisim doesnt not have atmega 16 chips so i cant simulate the circuit.
