DMX (Digital Multiplex) is a digital communications standard used to control stage lighting and special effects.
The TinkerKit DMX Master Shield from Arduino is an interface that enables you to connect to an Arduino board and drive DMX receivers at the same time. You can also create a shield 'stack'. This means that the DMX shield can sit right on top of any other Arduino shield which in turn, enhances the functionality of your Arduino board.

Arduino TinkerKits
The TinkerKit range from Arduino is the perfect platform to prototype Arduino-based designs without the need for breadboards or soldering irons. Whether it is for experimentation within the classroom or for new technology projects, TinkerKits aim for simple and quick set-up. The TinkerKit sensors and actuators connect up to the TinkerKit interface, the Sensor Shield, which in turn connects to your Arduino board. We offer various types of kits from base level to pro, and various sensor, actuator and shield singular components.
