Christmas Lights

Description :


The Christmas Lights application relies on your development talents to create a mesmerizing light display. Your task is to draw seven colored circles in a row and based on a timer change the intensity of each circle. When a circle is brightened its predecessor returns to its normal intensity.

This simulates the effect of a string of rippling lights, similar to the ones displayed during the Christmas Holidays.

The Christmas season is nearly upon us, and that means it’s time to choose your gifts, schedule the Christmas parties and take the Christmas lights out of the loft. The internet has made shopping and arranging parties more convenient — so far, so obvious — but it’s made Christmas lights easier to control too. In this article, we’ll show you how how to get started.

Instead of turning on and off your Christmas lights by flicking on and off a plug on the wall, you can do it on your phone. This is achieved using a smart plug — literally an internet-connected plug.


Simply connect all of your Christmas lights together using a 4- or 6-way extension lead, then into the smart plug, and you’ll be in business. Open the app on your phone, and you can turn your lights on and off, whether you’re in the same room or a different continent. You can also do more clever things, like automatically turning the lights on at sunset or connecting multiple lights on different plugs and controlling them independently.
