microcontroller based non isolated dimmer circuit

[easy electronics]

hi ,
i want to control phase angle using triac and microcontroller .
but i dont want to use opto coupler like moc3021,moc3020.
i want to make non isolated circuit .

why you want use non isolation circuit any reason?

thanks ud23 , thanks milan.rajik.
well mr ud23 i want to make cheapest dimmer using microcontroller.
microcontroller is necessory because of i also want to interface this with ir remote , and 7segment.

mr Milan.rajik i think that circuit is only for theoretical idea .

you need some special controller like in above link.But I would recommend isolation approach.

Which circuit you are referring to ?
