I got this awesome idea of lighting up my upright piano while tinkering with some RGB LED strips. The RGB LEDs emit light that gets reflected off the wall behind the piano, giving a stunning effect. The setup also includes a sound sensor circuit, with the help of which, the RGB LEDs change colour depending on how loud one plays notes on the piano!
Since no one has had such an idea and shared it on the net, I was on my own. Therefore I had a experiment quite a lot. However all my hard work has paid off well; my RGB LED lit piano looks great and compliments the Christmas tree very well indeed!
