Abstract
An ambient light control module and method of operating an ambient light control module selectively actuates light modules to provide a desired light color and intensity. The disclosed ambient light control module selectively actuates light modules that are controllable to provide desired colors. The light control module produces uniform signals across the several light modules such that each separate light module will emit the same color. The disclosed example light control module includes a microcontroller with a plurality of output channels including output compare channels and pulse width modulated channels. The output channels are matched to a common clock so that a uniform signal is emitted from any channel to provide the desired uniformity between lighting modules.
