AC PWM Dimmer Circuit For Arduino

This is testing Video of AC PWM Dimmer Circuit For Arduino. We controlled 15W lamp and it works fine. Later this circuit used to control speed of celling fan with RC-5 Remote Tech.
Link for circuit and Code is:

Please be safe while working with AC Voltages. It is Designed for 220V/50Hz Supply. For US standard circuit is to be reconsidered.
