It can be used to replace the communication cable between the mobile device, thereby ing a personal wireless network. It not only makes the integration of computers and communications become possible, but as it continues to progress, but also integrated terminal appliances, entertainment electronics and computers, communication systems, right, so that people in the home, office or public place can be achieved unified operation and control for the implementation of office automation and home communications has created good conditions. With the rapid development of electronic science and technology, especially with the large-scale integrated circuits, to human life brought fundamental change. Especially the development and application of SCM technology development, product now almost into the household. Control Based WIFI phone colorful lamp design is responsive to current wave of development of wireless control design work, which involved a typical application WIFI wireless communication technology is WIFI, which developed the foundation for the later study.In this paper, by phone WIFI PWM control angle for design. This article describes the system structure and working principle of a WIFI control PWM dimming RGB lights. Specifically addressed the three primary colors mixed light under PWM control principle; and the use of advanced WIFI technology works under control in order to determine the overall design of the program and debug procedures. Key words: WIFI; tricolor mixed light; PWM c
