can i control the below triac board using uC?
Is it by making the 12V on/off ?

 

Hello ,
looks like the 12V input is the control input of the board , so i believe your assumption is correct
and in this case you can control with with a uC by controlling a relay that connect 12 VDC

so.
i have to connect uC to mosfet and mosfet to this board 12V isnt it ?
 

You can even lower resistor value for optotriac diode and use 5V instead 12V.


Transistor drive optotriac:
