Hello friends,
I want c code for pic16f877a controller for the application of Digital AC Lamp intensity controller.
Please any one help?

Thank you
 

hi

you can use the pwm to vary the intensity of the output.
use MOC series couplers to trigger a triac to vary the intensity of the ac lamb
you will find many sample circuits just by trying google
 

Re: Digital AC Lamp intensity control using pic16f877a microcontroller

You just control the conduction angle of the AC wave by firing the TRIAC using a PWM wave.
 

Friends thanks for your reply,
I don't know how to fire the triac using pic16f877a controller?
Please help me with some sample code?

Thank you
