The diploma thesis presents remotely managed DMX lighting controller using wireless network. With the help of WeMos platform, it enables the system to control RGB LEDs. The beginning of the thesis presents protocols that are used in stage lighting, compares them and gives a detailed description of the DMX protocol. The following chapter describes the architecture of the system, which includes descriptions of important parts of source code, wireless communication and connection between all components of the system. Next it presents the functioning of the final product and describes it through steps of source code. Functioning is also shown on a practical example and at the end it is followed by results of tests and optimisation of the system.
