To fulfill this requirement, we built one COM port as input port and 8 PWM(Pulse Width Modulation) output port, each of which can adjust light intensity of one LED, hence one board can control two 3-color LED boards. |

In ideal situation, we need nine 3-color LED boards work at the same time. In other word, we need four MCU boards, and we finally use two as prototype. |
