hi i want make a project which involves making of a tempearature controller using microcontroler, moc3041 and triac bta41-600b ? i want to know how can i vary the firing angle? is it possible by pwm?
 

microcontroller temperature control

Use a 50 or 60Hz interrupt on change based on power sinusoidal variation and an standard optocoupler. On every sinusoidal rising edge, start a counter and number a variable time period from 0 to 20ms (50Hz) or 0 to 16mS (60Hz). Fire the triac via MOC optocoupler at any time below 0 and 20mS (or 16ms). Firing near 0mS will produce a full load, delayed firing will decrease the energy on the load down to 0.
 
temperarure controller using microcontroller

Use a 50 or 60Hz arrest on change based on ability sinusoidal aberration and an accepted optocoupler. On every sinusoidal ascent edge, alpha a adverse and amount a capricious time aeon from 0 to 50Hz or 0 to 60Hz...

You can't use MOC3041, it only connects at zero-crossings, you better use MOC3021
