PROGRAMMABLE LED ILLUMINATION OF A PRIVATE HOUSE
This Christmas, our house in Novato is decorated with huge, shining, white space invaders and bright green Christmas trees. The phrases "Merry Christmas!" and "Happy New Year!" are displayed as a scrolling text. In terms of technology, our house has the most sophisticated Christmas decorations.
This illumination cost about $400. It consists of 16 16.5 feet long LED strips. An Arduino Mega processor controls 4800 lights via 8500 resistors.
Additional components are three 5 V power supplies, connectors of the LED strips, wires and three voltage stabilizers that protect LEDs against voltage drops.
