    That was actually a @blacey comment.

      @hek * This sketch is extensible to support more than one MOSFET/PWM dimmer per circuit.
      How do you add more outputs to this? I would like to add PWM 5 and 6 to this. I am using the EasyIot controller. @blacey

      @boblasure So you effectively want 3 children, one for each PWM? You will need to extend the sketch to handle two additional pins/children. @korttoma has already done the work...

      Here is his sketch that handles four channels.

            Can this dimmer sketch be used to control the speed of a fan ? If yes then what are the changes I need to do to this sketch. As part of a project I am working on, I intend to control a AC 230V fan using arduino. I was planning to create a sketch which explicitly controls a AC FAN.
            By doing this am I reinventing the wheel or someone has done this already which I can use.

                I have the dimmer circuit with me already. I am looking for the sketch to integrate this with the sensor and send message to the gateway using MQTT for controlling the speed of the fan.

                Note: I am using a custom controller build using Ruby on Rails(WIP). and ruby-mqtt to send message to the MQTT gateway which is running mysensor code.

                  @mainali I don't think I have what you're looking for :( ...

                      I have kind of implemented the fan control with a new message type V_FAN, but anyways I will check this out and revert after testing

                        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.

                          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 ).

                            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!!!
