I'm made this minimal montage with triac and photoresistor...and work fine! Is good alwais for application with arduino or atmega microcontrollers.http://www.youtube.com/watch?v=ZOd4bO7YI-I

 

WOW! Good job on the project and the tutorial. Now you need to learn about safe practices! Open wires with line voltage, (220VAC no less!!!), hot lamp directly on cloth?? Also, a warning about the ENORMOUS jump in volume when the music starts would be welcome.

 

So what is new or newsworthy, the first time I did that was in 1966.

You're ahead of me. I didn't do that until 1980
