The device will be primarily controlled by a master control microprocessor which will store and execute the primary operation software A second microcontroller will be used to interface with the master controller with all input/output devices The output will be displayed via 100 individually controllable RGB LEDs A minimum 16 scale color wheel will be used The LEDs will be driven by dedicated controllers to limit strain on the processor and improve overall processing speed The input will be taken through 100 individual infrared sensing circuits Multiplexers and demultiplexers will be used accordingly on inputs and outputs to limit the number of connections to the microprocessor The device will be Bluetooth enabled through the use of a Bluetooth chip and affiliated circuit to allow connection to the users Android based device A USB connector will be available on the PCB for programming each of the microcontrollers A USB connector will be available on the surface of the device with a proper circuit allowing the user to communicate data during programming mode A commercially available power supply will be used which meets the power consumption requirements of the device A power control circuit will be generated which will prevent damage to the device in the event of overload or other fault, and include appropriate power distribution to the device components Research Existing Projects and Products The existing project designs that are referenced in this chapter of the report will appear in the following sequence: First, the projects will be partitioned between commercial and hobbyist/freelance designs. Second, project designs that are based on a 3D design will be referred to first, and 2D designs will appear after them. Third, projects that have no interactive features (animation-only) will be mentioned first. Projects that have interactive features will appear last. Originally, the group was split between 2 design schemes. Half the group wanted an interactive 3D LED cube, and the other half wanted an interactive 2D LED array panel. To determine whether the group wanted to go with a 3D cube or 2D panel design, the following commercial and hobbyist designs were sought out and cataloged. Most of the projects referred to in this section will be interactive. However, these animation-only projects still provide some unique design features that will be put into consideration by the group.
