Control AC bulb with Arduino AC Dimmer

This this video shows how to use AC Light dimmer to control AC bulb using AC dimmer and Arduino.
I opened the sketch File->Examples->RBDdimmer->SerialMonitorDim where you can control the light from command line of Serial Monitor but due to issue explained in the video, it doesn't work properly and code needed to be modefied. It might work in region with 50Hz which I have not tesed.
