    All the dimmer examples does is to change the level on an PWM output according to a 0-100% dimmer slider in the controller. What you connect to the PWM output is up to you. In the example sensor device I posted I have connected a transistor that controls the speed of a 12VDC fan.

    I have also maid another sensor that shows as a dimmer in the controller but in the arduino it controls 3 relays instead ( there are not so many rules you have to follow here you can create what you need, that's the beauty of MySensors ).

      Can the dimmer led actuator example be used to dim a AC 60w incandescent bulb connected 220v connection. If yes what are the modification needed.

      when it comes to controlling the speed of a FAN or dimming a normal tungsten filament bulb. I have found so many answers but not a single one which explains all.

      Dimming AC current is far more complex than dimming DC from the hardware perpective.
      Do a search on the internet about it and come back with a solution that fits your needs.

          This circuit might help with what you are doing. See attached. Try building this circuit and connect "signal & ground" to dimmer LED actuator PWM. Again I can't stress enough be careful with AC power!!!
