Hi,
Im new to electronics so i have some issues on reading datasheet

I want to control a halogen lamp using triac (Q4010L5) and optocoupleur (MOC3021).

I want to know the best value for (R1-R2-R5), to not dammage the triac and optocoupleur.

"I didnt mention here the zero crossing detector part that will give implusion to RB1".
Thanks for your time.
 

if you want to limit the max gate current to 1A say, then R1 + R2 = 325 ohm, note they must be rated for >200V each to avoid them breaking down ...
