Control Intensity oof Bulbs using Microcontrollers

baberjaved said:

I wanted to know what device can be used in order to light up and control the intensity of several 60Watt bulbs using a microcontroller. Obviously the microcontroller will only be used to control the switching of the bulbs and controlling the firing angle and the bulbs would be getting their power from Main 220V AC. I think TRIAC can be used for this but i wanted to know if theres any better alternative design and are there any power consumption/wattage issues involved that i need to worry about?

A simple solution would be to use solid state relays. Their inputs can be driven directly with digital output pins from a micro. They use an internal triac for the AC voltage switching. You could apply PWM digital signal to the relay to get a dimming function.
