ABSTRACT:
A plurality of color LEDs are commonly coupled to a source of operating supply. A plurality of switching transistors and current limiting resistors in series therewith are coupled to the color LEDs to control the current there through in response to switching transistor conduction. A microcontroller having an input signal and a plurality of outputs configured in response thereto is operatively coupled to the plurality of switching transistors to control the conduction and thereby illumination output of the color LEDs to achieve incremental color blending.
