Hey guys I am dealing with above titled project,
I am using PWM CODES But i am facing a problem that my ac filament is blinking and not dimming
how can I solve the problem IN ORDER for the filament lamp to dim and not blinking.
THANKS IN ADVANCE
 

you need to increase the frequency of the PWM... 100Hz may work.

Edited:
I supposed you mean a small filament bulb supplied by a DC current otherwise the solution would be totally different.

HE is using small filament lamp with an AC current
Do you have any other solution I will appreciate that
 

Ok... Let us continue to the next question, since you are not a talker :)

You said the bulb is blinking. This means you are able to send a signal from your circuit (working on low voltage DC) to change the current in a load (the bulb) connected to the main power (240Vac, 50Hz).

What is your actual interface or driver? I have many possibilities in my mind ;)
