Arduino compatible Christmas tree

Arduino compatible Christmas tree

I do not understand this “Arduino” device. But I commend you on your perseverance in solving the problem with such a complicated tool. In my laboratory, I invented a similar contrivance that uses fewer components. A piece of phenolic insulating board was cut into the shape of a tree. Placed upon it are a number of gas discharge tubes (type NE-2 etc.) with various gases within to provide the colors (e.g. orange, blue, green, and such). Ten megohm carbon composition resistors and 0.1uF condensers were connected as relaxation oscillators to provide a pleasant blinking rate. Power consumption is exceptionally low. It has operated for months on a 90v B battery that was already depleted so as to be of no further use in a radio. Thomas A. Edison West Orange, NJ December the 20th, 1912
